Romans 2:17 But if you bear (2SPPI) the name "Jew " and rely (2SPMI) upon the Law and boast  (2SPMI) in God, (NASB: Lockman)

Greek: Ei de su Ioudaios eponomaze (2SPPI) kai epanapaue (2SPMI) nomo kai kauchasai (2SPMI) en theo
Amplified: But if you bear the name of Jew and rely upon the Law and pride yourselves in God and your relationship to Him,
(Amplified Bible - Lockman)
NLT: If you are a Jew, you are relying on God's law for your special relationship with him. You boast that all is well between yourself and God. (
NLT - Tyndale House)
Phillips: Now you, my reader, who bear the name of Jew, take your stand upon the Law, and are, so to speak, proud of your God. (
Phillips: Touchstone)
Wuest:  Now, assuming, as for you, that you bear the name of Jew, and have a blind and mechanical reliance on the law, and boast in God, (Erdmans
Young's Literal: Lo, thou art named a Jew, and dost rest upon the law, and dost boast in God,

BUT IF YOU BEAR THE NAME JEW: Ei de su Ioudaios eponomaze (2SPPI): (Ro 2:28,29; 9:4-7; Ps 135:4; Isa 48:1,2; Mt 3:9; 8:11,12; Jn 8:33; 2Co 11:22; Gal 2:15; Eph 2:11; Phil 3:3, 4, 5, 6, 7; Rev 2:9; 3:1,9) (See Naves Topics Formalism; Hypocrisy; Self-Righteousness Torrey's Topic Hypocrites)

If (ei) is what is referred to as a "first class conditional" statement and signifies that what follows is assumed to be true. It can often be translated with the word "Since" ("Since you bear the name Jew" which they did indeed bear)

Bear (2028) (eponomazo from epí = upon + onomázo = to name) means to  call, to classify oneself by means of a name, title, or attribution.

Every "boast" of the Jew in this passage concerns their possession of  God's law. Although the Jew certainly should gratefully receive the law as a gift from God, Paul emphasizes that the possession of the law does not result in a declaration of righteousness before God and that is the great need of every man, both Jew and Gentile. Like a prosecuting attorney, Paul builds his case against the Jew  based on this question -- "You have the law, do you keep it? You can see how others break the law, do you see how you break it also?"

As we have said many times in Romans, the Jewish leaders in Paul's day interpreted (rather "misinterpreted") the law in such a way that one might consider themselves justified by the law. In the Sermon on the Mount, Jesus sought to directly expose the error of such a deadly, deceptive misinterpretation (and misapplication), explaining in essence, that it was not so much what a person was externally, but what they were internally, in their heart (See discussion of the argument of Jesus beginning in the notes on Mt 5:19, 20). The problem of the Jewish interpretation (and of all fallen men for that matter) is that we only seek to apply God’s law to our external actions, which misses the most important point that God desires to apply His law to our heart attitudes (cp God's law in our minds and written upon our hearts - Hebrews 8:10 - note)

Jew (2453) (Ioudaios)

Hebrew distinguishes a Hebrew-speaking Jew from a Greek-speaking one.

Jew distinguishes a Jew from a Gentile, and denotes nationality.

Israelite is the most august title of all, speaking of the fact that the Jew is a member of the theocracy, and thus an heir of the promises (Trench).

Previously called Hebrews and Israelites, by the first century “Jew” had become the most common name for the descendants of Abraham through Isaac. “Jew” is from “Judah,” (“praise”), one of the 12 tribes and the designation for the southern half of Solomon’s kingdom after his death. From the time of the Babylonian captivity, the whole race bore this title. Their great heritage, however, (cf. Ge 12:3) became a source of pride and complacency (cf. Jonah 4:2; Mic 3:11, 12; Mt 3:7, 8, 9; John 8:31, 32, 33, 34, 40, 59), which led to judgment instead of “praise.” He could and should have become a "guide" and "light" to those in darkness (Ro 2:19). So Paul is showing the self-righteous Jews, boasting in their status as God's chosen people, that just being a Jew is not sufficient for salvation.

The ISBE entry notes that

"Jew" denotes originally an inhabitant of Judah (2 Kings 16:6 applies to the two tribes of the Southern Kingdom), but later the meaning was extended to embrace all descendants of Abraham. In the Old Testament the word occurs a few times in the singular. (Esther 2:5; 3:4, etc.; Jeremiah 34:9; Zechariah 8:23); very frequently in the plural in Ezra and Nehemiah, Esther, and in Jeremiah and Daniel. The adjective in the Old Testament applies only to the "Jews' language" or speech (2Kings 18:26,28 parallel Nehemiah 13:24; Isaiah 36:11,13). "Jews" (always plural) is the familiar term for Israelites in the Gospels (especially in John), Acts, Epistles, etc. "Jewess" occurs in 1 Chronicles 4:18; Acts 16:1; 24:24. In Titus 1:14 (note) a warning is given against "Jewish fables" (in Greek the adjective is found also in Galatians 2:14). The "Jews' religion" (Ioudaismos) is referred to in Galatians 1:13,14. (James Orr)

AND RELY UPON THE LAW: kai epanapaue (2SPMI) nomo (Ro 2:23; Ro 9:4,32; Jer 7:4, 5, 6, 7, 8, 9, 10; Zep 3:11; Lk 10:28; Jn 5:45; 7:19; 9:28,29)(cp only "doers...justified" Ro 2:13)

Rely (1879) (epanapauomai from epí = upon + anapaúomai = to rest <> from aná = again + paúo = cease, give rest)conveys the basic meaning of to rest on. The idea is to refresh oneself back upon anything.  It describes finding "comfort" through confident dependence on something, trust in and in context trusting in the Law but not being doers of it, which pictures a blind and mechanical reliance on the Mosaic law.

Epanapauomai is used only here here and Luke 10:16

And if a man of peace is there, your peace will rest upon him; but if not, it will return to you.

It means to continue, remain with the sense of remaining upon. In the OT (LXX), this word is describes the Spirit of God "resting" on men (see below - Nu 11:25, 26) So here the picture Paul paints is of a spiritually blind mechanical "resting upon" or relying upon the Mosaic Law. The present tense of this verb pictures this as their continual attitude. Paul says that you continually (present tense) rest upon with a blind and mechanical reliance on the Mosaic law.

From (Ro 2:17-29) God shows that His judgment is based on reality not religious profession.

Epanapauomai is used 8 times in the Septuagint (LXX) (Nu 11:25, Nu 11:26, 2 Ki. 2:15, 2 Ki. 5:18, 2Ki. 7:2, 2Ki. 7:17, Ezek. 29:7, Mic. 3:11) in some cases meaning literally "leaning upon" and in others describing the Spirit "resting upon" men Moses recording for example...

Then the LORD came down in the cloud and spoke to him; and He took of the Spirit who was upon him and placed Him upon the seventy elders. And it came about that when the Spirit rested upon them, they prophesied. But they did not do it again. 26 But two men had remained in the camp; the name of one was Eldad and the name of the other Medad. And the Spirit rested upon them (now they were among those who had been registered, but had not gone out to the tent), and they prophesied in the camp. (Nu 11:25, 26)

AND BOAST IN GOD: kai kauchasai (2SPMI) en theo: (Is 45:25; 48:2; Mic 3:11; Jn 8:41) (Ro 2:23, 3:27, 4:2 contrast real "boasting" Ro 15:17 & real praise Ro 2:29):

NIV = "brag about your relationship to God"

Boast (2744) (kauchaomai akin to aucheo = boast + euchomai = pray to God <> auchen = neck which vain persons are apt to carry in proud manner) means to boast over a privilege or possession. The idea is to take pride in something (in a bad sense - Ro 2:23-note, in a good or legitimate sense - Ro 5:2-note, Ro 5:3-note; Ro 5:11-note)

Kauchaomai is translated in the NAS as - boast(24), boasted(1), boasting(3), boasts(2), exult(3), glory(2), take pride in(1).

Fallen men have no grounds for boasting in the presence of God (1Co 1:29, James 4:16) but instead should boast in God (1Co 1:31, from Jer 9:23, 24, cp 2Co 10:17). And so Paul writes that...

that no man should boast before God, but by His doing you are in Christ Jesus, who became to us wisdom from God, and righteousness and sanctification, and redemption, that, just as it is written, "LET HIM WHO BOASTS, BOAST (present imperative = command to continually boast) IN THE LORD." (1Cor 1:29, 30, 31)

Paul however did want the Corinthians to boast in the work of God in and through him (2Co 5:12). Paul himself boasted about the readiness (readiness of mind, eagerness) of the saints at Corinth to contribute to the fiscal needs of the saints at Jerusalem (2Cor 9:2 - his boasting in them here had as its object the calling of the Corinthians back to their original readiness to participate in the offering project.) As noted in the list of NT uses below, kauchaomai is frequent in the letters to the Corinthians. Notice that Paul emphasizes what it is we as saints should genuinely boast about in regard to ourselves...

2Co 10:30 If I have to boast, I will boast of what pertains to my weakness.

2Co 12:1 Boasting is necessary, though it is not profitable; but I will go on to visions and revelations of the Lord...5 On behalf of such a man will I boast; but on my own behalf I will not boast, except in regard to my weaknesses. 6 For if I do wish to boast I shall not be foolish, for I shall be speaking the truth; but I refrain from this, so that no one may credit me with more than he sees in me or hears from me. 7 And because of the surpassing greatness of the revelations, for this reason, to keep me from exalting myself, there was given me a thorn in the flesh, a messenger of Satan to buffet me-- to keep me from exalting myself!8 Concerning this I entreated the Lord three times that it might depart from me. 9 And He has said to me, "My grace is sufficient for you, for power is perfected in weakness." Most gladly, therefore, I will rather boast about my weaknesses, that the power of Christ may dwell in me.

Gal 6:13 For those who are circumcised do not even keep the Law themselves, but they desire to have you circumcised, that they may boast in your flesh. 14 But may it never be that I should boast, (believers give the credit for all they are and have to the Lord Jesus Christ and His efficacious work on Calvary) except in the cross of our Lord Jesus Christ, through which the world has been crucified to me, and I to the world.

Comment: Beloved, let us exult joyfully in one thing, the Cross of Christ, letting this be our single minded focus, our sole passion and joy. Christ crucified is to forevermore be our boast and exultation so that He Alone receives the glory and honor for every good thing in our lives and every bad thing that God turns for good. Such supernatural boasting happens when we appreciate and live in the glorious truth that we have been crucified with Christ on His old rugged cross. This radical truth transforms our lives that were in the gutter so that they are now directed toward glory, the glory of the cross of Christ. (cp Gal 2:20 - see notes). Next time you catch yourself being tempted to boast, ask yourself "In this boasting, is it ultimately in some way tied to boasting in the almighty Cross?" If not, you might want to check that heart attitude or the words that proceed from that heart attitude (cp Mt 15:18, 19, Mt 12:36 where "careless" = argos = "not working", bearing no fruit type words [see study of words = rhema])

As Paul explained in the famous soteriological passage in Ephesians...

Eph 2:8, 9 (see notes) For by grace you have been saved through faith; and that not of yourselves, it is the gift of God; 9 not as a result of works, that no one should boast.

In Philippians Paul speaking of true believers stated that...

we are the true circumcision, who worship in the Spirit of God and glory in Christ Jesus and put no confidence (do not boast) in the flesh (Php 3:3 - see notes)

James writes...

But let the brother of humble circumstances glory (present imperative = command to continually boast)  in his high position;

Here are the 37 uses of kauchaomai in the NT - Ro 2:17, 23; 5:2, 3, 11; 1Co. 1:29, 31; 3:21; 4:7; 13:3; 2Co. 5:12; 7:14; 9:2; 10:8, 13, 15, 16, 17; 11:12, 16, 18, 30; 12:1, 5, 6, 9; Ga 6:13, 14; Ep 2:9; Php 3:3; Jas. 1:9; 4:16

There are 12 uses of kauchaomai in the Septuagint (LXX)- Jdg. 7:2; 1Sa 2:3, 10; 1Ki. 20:11; 1Chr. 16:35; Ps 5:11; 32:11; 49:6; 94:3; 149:5; Pr 20:9; 25:14; 27:1; Je 9:23, 24; Da 5:1, 6

Kauchaomai  is used in the OT of any proud and exulting joy and is expressive of triumphant, rejoicing confidence in God (eg, 1Chr 16:35, Ps 5:11; 32:11). This word combines ideas of jubilation and confidence into one word to describe "joyful confidence".

Jdg 7:2 (see notes) And the LORD said to Gideon, "The people who are with you are too many for Me to give Midian into their hands, lest Israel become boastful (Heb = pa'ar = to beautify, to glorify; Lxx = kauchaomai), saying, 'My own power has delivered me.'

NIDNTT adds that...

 In classical Greek the verb kauchaomai is found from Sappho onwards. Homer uses instead euchomai, pray, ask, wish. The tragedians and orators use aucheo, boast, plume oneself. Intrans. kauchaomai means to boast, vaunt oneself, be proud. With the prepositions en, epi, peri, huper, eis, or kata, it means to boast of a person or thing. The trans. form also occurs. The compound vb. enkauchaomai has the same meaning. katakauchaomai is used particularly with reference to the situation of an object, and may be translated to vaunt oneself against someone, to treat someone in a derogatory or contemptuous manner.  Kauchema (Pindar) refers to the subject of boasting, to the words used by the boaster, and occasionally also to the act of boasting, although for the latter (especially in the NT) the noun kauchesis is more frequently found. Kauchesis (Epicurus) can likewise on occasion be used to denote the subject of boasting.  Although the ancient Greeks recognize legitimate pride in oneself (e.g. Homer, Il., 6, 208), there is a clear appreciation of the distinction between this and unwarranted bragging, which was pilloried by the satirists and others. Plutarch also attacked ostentation in an essay on Self-praise without Envy.

The Jew continually (present tense) boasted in God as the covenant God of Israel and that they were His peculiar people. Jesus corrected their faulty misconception that God was their Father accusing the Jews (who paradoxically had believed in Him in John 8:30-31 indicating that their belief was only a profession or mental/intellectual assent and not a changed/circumcised heart!) declaring ...

"You are doing the deeds of your father." They said to Him, "We were not born of fornication; we have one Father, even God." Jesus said to them, "If God were your Father, you would love Me; for I proceeded forth and have come from God, for I have not even come on My own initiative, but He sent Me. "Why do you not understand what I am saying? It is because you cannot hear My word. "You are of your father the devil, and you want to do the desires of your father. He was a murderer from the beginning, and does not stand in the truth, because there is no truth in him. Whenever he speaks a lie, he speaks from his own nature; for he is a liar, and the father of lies. (John 8:41-44)

Even a Divinely revealed religion provides no security to its professor if it is devoid of reality. It makes no difference whether it is the "Jews’ religion" at the beginning of their existence as a nation or Christianity today. Profession does not always signify possession!

In the above verses Paul is directly addressing the Jew. He shows that the Jew "rested" on The Law, —on having it; and were proud that the will of the true God had been revealed to them, that they "knew" that will, and were therefore able to "approve the things that: are excellent." The Jews developed a false confidence in themselves as guides, lights,  correctors of the foolish, teachers, because they felt (self deception) that in the law they had "the form of knowledge and of the truth." Their problem was that they did not apply the Law to themselves -- their teaching, preaching, saying what folks should be, abhorring idols, glorying in The Law! The result was that the very Name they boasted in was blasphemed among the Gentiles because of their blatant selfishness, pride, covetousness, and general wickedness!

William Newell applies Paul's truths to "Christians" writing that...

"If we should thus apply this passage (Romans 17-29), must it not read something like this?—

"If you bear the name of a Christian, and rest on having the gospel, and glory God, and know His will, and approve the things that are excellent, being instructed out of the gospel; and are confident that you yourself are a guide of the blind, having in the gospel the form of knowledge and of the truth"

— Then would follow the searching questions of Romans 2:21-22; for do we not know teachers that teach others, but refuse to follow their own teaching? And preachers that denounce stealing, but are accused by the world of being themselves money-grabbers? So it would read,

"You who glory in the gospel, through your disobedience to the gospel, do you dishonor God? The name of God is blasphemed among non ‘church-members’ because of you! Church-membership indeed profits if you are an obeyer of the gospel; but if you are a refuser of a gospel-walk, your ‘church-membership’ has become non ‘church-membership.’ If therefore a non ‘church-member’ obeys the gospel, shall not his non ‘church-membership’ be reckoned for ‘church-membership’? And shall not non ‘church-members, ‘if they obey the gospel, judge you, who with the letter and ‘church-membership’ are a refuser of a gospel-walk? For he is not a Christian who is one outwardly, nor is that ‘church-membership’ which is outward in the flesh; but he is a Christian who is one inwardly; and ‘church-membership’ is that of the heart, in the Spirit not in the letter, whose praise is not of men, but of God."  (Romans 2)

 

Romans 2:18 and know (2SPAI) His will and approve (2SPAI) the things that are (PAPNPA) essential, being instructed (PPPMSN) out of the Law, (NASB: Lockman)

Greek: kai ginoskeis (2SPAI) to thelema kai dokimazeis (2SPAI) ta diapheronta (PAPNPA) katechoumenos (PPPMSN) ek tou nomou
Amplified: And know and understand His will and discerningly approve the better things and have a sense of what is vital, because you are instructed by the Law;
(Amplified Bible - Lockman)
NLT: Yes, you know what he wants; you know right from wrong because you have been taught his law. (
NLT - Tyndale House)

Phillips: You know his plan, and are able through your knowledge of the Law truly to appreciate moral values.  (Phillips: Touchstone)

Wuest:  and have an experiential knowledge of His will, and after having put to the test for the purpose of approving the things that differ, and having found that they meet your specifications, you put your approval upon them, being instructed in a formal way in the law, (Erdmans
Young's Literal:  and dost know the will, and dost approve the distinctions, being instructed out of the law,

AND KNOW HIS WILL AND APPROVE THE THINGS THAT ARE ESSENTIAL: kai ginoskeis (2SPAI) to thelema kai dokimazeis (2SPAI) ta diapheronta (PAPNPA): (Dt 4:8; Ne 9:13,14; Ps 147:19,20; Lk 12:47; Jn 13:17; 1Co 8:1,2; Jas 4:17) (approve Phil 1:10; 1Th 5:21; Heb 5:14)

Know (1097) (ginosko) (present tense) means taking in knowledge in regard to something or someone, knowledge that goes beyond the merely factual, thus Wuest translates it "have an experiential knowledge". By extension, the term frequently was used of a special relationship between the person who knows and the object of the knowledge. For example, ginosko, was often used of the intimate relationship between husband and wife and between God and His people.

Will (2307) (thelema from thelo = to will) means what one wishes or has determined shall be done or that which is desired or wished for. It refers to a desire which proceeds from one’s heart or emotions. This term expresses the result of one’s purpose or desire.

Thelema has both an objective meaning (“what one wishes to happen”) and a subjective connotation (“the act of willing or desiring”). The word conveys the idea of desire, even a heart’s desire, for the word primarily expresses emotion instead of volition. Thus God’s will is not so much God’s intention, as it is His heart’s desire, His gracious disposition. It refers to His will not as a demand but an inclination of pleasure towards that which is liked, which pleases and creates joy. God’s will signifies His gracious disposition toward something or what God Himself does of His own good pleasure.

Approve (1381) (dokimazo from dokimos = tested, proved or approved, tried as metals by fire and thus purified from dechomai = to accept, receive) (Click for in depth study of dokimazo) means  means to assay, to test, to prove, to put to the test, to make a trial of, to verify, to discern to approve.

Paul is saying "You Jews...

after (continually = present tense) having put to the test for the purpose of approving the things that differ (essential), and having found that they meet your specifications, you put your approval upon them." (Wuest)

Dokimazo involves not only testing but determining the genuineness or value of an event or object. That which has been tested is demonstrated to be genuine and trustworthy.

Dokimazo was used in classic Greek to describe the assaying of precious metals (especially gold or silver coins), usually by fire, to prove the whether they were authentic and whether they measured up to the stated worth. That which endures the test was called dokimos and that which fails is called adokimos

Dokimazo means to put to the test for the purpose of approving, and finding that the person tested meets the specifications prescribed, to put one’s approval upon him. For example Paul writes that unregenerate mankind

"did not approve (dokimazo) of having God in knowledge, God gave them up to a disapproved mind, to do the things not seemly." (Young's literal translation; see notes on Romans 1:28)

In this incredible verse fallen men presumptuously put God to the test for the purpose of approving Him to see He if He would meet the specifications which they laid down for a God who would be to their liking! But sinful man did not stop there, for finding that He did not meet their specifications, they refused to approve (dokimazo) Him as the God to be worshipped or have Him in its knowledge! They tested the infinitely precious God as they would a mere coin, and chose to turn aside from Him! A similar audacity

Dokimazo means to make a critical examination of something to determine its genuineness. Dokimazo was used in a manuscript of 140AD which contains a plea for the exemption of physicians, and especially of those who have "passed the examination (dokimazo)". Dokimazo was thus used as a technical expression referring to the action of an examining board putting its approval upon those who had successfully passed the examinations for the degree of Doctor of Medicine. 

Essential (1308) (diaphero from dia = transition or separation + phéro = carry, bear) means literally to carry two ways and so to carry different ways and then comes to mean "to differ”. As used in this verse (and in Philippians 1:10) diaphero (ta diapheronta) refers to "the things different" and thus has the meaning of distinguishing things that are different.

Diaphero  is used of those moral and spiritual concepts and actions which involve delicate and keen distinctions, those that require a deep and keen discernment to recognize. Not the ordinary, everyday, easily understood spiritual obligations, but the finer points of the Law. It speaks of those things that are superior, vital, that surpass, that excel!

Vincent comments that diaphero...

may also mean the things which differ; in which case we shall render provest instead of approvest. The sense will then be: thou dost test with nice discrimination questions of casuistry. Compare Philip. 1:10. The latter interpretation seems preferable, being borne out by the succeeding being instructed.

BEING INSTRUCTED OUT OF THE LAW: katechoumenos (PPPMSN) ek tou nomou: (Ro 15:4-note; Ps 19:8; 119:98, 99, 100,104,105,130; Pr 6:23; 2Ti 3:14, 15-note; 2Ti 3:16, 17-note)

Instructed (2727) (katecheo from katá = down or intensive + echeo = sound, our English "echo") (see related word sounded forth = execheo) means to literally to sound down on or into the ears. From this the derived meaning is “to inform” or “to instruct orally.” The idea is to re-sound, to re-echo, to teach by by insistent repetition into the ears as the Arabs do when learning the Koran (learning aloud). The present tense indicates they were continuously being (passive voice) instructed out of the Law.  Continuously systematically instructed through catechetical and synagogue instruction. This formal instruction is the basis of the critical discrimination or discernment.

Katecheo is used 8 times in the NAS (Luke; Acts 3x; Romans; 1 Corinthians; Galatians) and is translated instruct, 1; instructed, 2; taught, 2; teaches, 1; told, 2; .

The idea is to teach by word of mouth, to teach in systematic or detailed manner, to indoctrinate ("catechize"). To drill a teaching into another which as alluded to can imply learning by repetition.

Luke wrote his Gospel so that Theophilus might know the certainty of those things concerning which he had been informed orally or catechized (Luke 1:4).

so that you might know the exact truth about the things you have been taught (katecheo) (Luke 1:4)

 Apollos was catechized or orally informed, Luke writing that he...

had been instructed (katecheo) in the way of the Lord; and being fervent in spirit, he was speaking and teaching accurately the things concerning Jesus, being acquainted only with the baptism of John (Acts 18:25)

The Jews had been orally informed by Paul in (Acts 21:21, 24)

As used here in Romans 2:18, Paul says that the Jews were taught orally out of the law.

Paul preferred to speak five understandable words than ten thousand words in another language, so that he could then orally teach others

"however, in the church I desire to speak five words with my mind, that I may instruct others also, rather than ten thousand words in a tongue." (1Cor. 14:19)

God commands that the person who has been orally informed about His Word should share with him who orally teaches

And let the one who is taught the word share all good things with him who teaches. (Gal. 6:6).

In summary, teaching involves the oral passing on of information about the things of God. It is catechizing, informing by word of mouth.

Katecheo is the source of our English word “catechism” - those doing the teaching were called catechists and those receiving it were called catechumens.

"Catechized" is idea of oral instruction especially associated with teaching by repetition. Both at home and in the synagogues, Jewish boys in particular were systematically and thoroughly instructed out of the Law. The Law was read and explained every Sabbath. Not only rabbis but also many other Jewish men memorized large portions of the OT, which they often recited in public as a demonstration of piety. It is ironic that ancient Jews considered wisdom to consist of acting according to the knowledge one had, whereas the ancient Greeks simply equated wisdom with knowledge. By New Testament times, however, many Jews, especially the religious leaders, had, in practice, accepted the Greek view of wisdom. Whether they did so intentionally or not, the consequence was that they felt content with merely knowing God’s law and had little desire or motivation to obey it. They knew much but obeyed little.

We today recognize the spiritual blindness of the Jew, but the blade cuts both ways. The sword that pierces the heart of the religious Jew also pierces ours. It is easy to imagine we are okay because we know so much more about the Bible than the average person on the street, especially in this day of Biblical illiteracy. We can read the Bible in twenty-five versions if we want. Some of us carry around Bibles that have as many as eight parallel translations. It is a great temptation for the pastor to imagine that, as he struts to the pulpit carrying his Hebrew Bible in one hand and the Greek in the other, he is okay, when in fact he may have a heart of stone.

 

Romans 2:19 and are confident (2SRAI) that you yourself  are (PAN) a guide to the blind, a light to those who are in darkness (NASB: Lockman)

Greek: pepoithas (2SRAI) te seauton hodegon einai (PAN) tuphlon, phos ton en skotei:

NLT: You are convinced that you are a guide for the blind and a beacon light for people who are lost in darkness without God. (

Phillips: You can, therefore, confidently look upon yourself as a guide to those who do not know the way, and as a light to those who are groping in the dark. (

Young's Literal:  and hast confidence that thou thyself art a leader of blind ones, a light of those in darkness,

AND ARE CONFIDENT THAT YOU YOURSELF: pepoithas (2SRAI) te seauton: (Pr 26:12; Isa 5:21; 56:10; Mt 6:23-note; Mt 15:14; 23:16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26; Mk 10:15; Jn 7:46, 47, 48, 49; 9:34,40,41; 1Co 3:18; 4:10; 8:1,2; Rev 3:17,18)

Confident (convinced, persuaded, trust) (3982) (peitho -- Thayer says it derives from the root meaning `to bind'; allied with pistis, fides, foedus, etc; see study of the antonym = apeitheo) means literally to persuade or induce by words to believe (Acts 19:26, Mt 27:20, Ro 14:14).
