LOOKING (continuously = one's lifestyle as manifest by his or her choices) FOR: prosdechomenoi (PMPMPN):  (Lu 2:25, 38 Lu 12:35, Mk 15:43,  Acts 24:15 , 1Cor 1:7 Php 3:20,21,1Th 1:10, 2Ti 4:8, Heb 9:28,2Pet 3:12,13-14, Jude 1:21, 1Jn 3:3)

For an excellent Mp3 message on Titus 2:11-15 listen to John Piper - Our Hope: The Appearing of Jesus Christ

Keathley introduces verse 13 commenting that...

Having mentioned this present and temporary age, the apostle quickly moved to the age to come that will be ushered in with the glorious appearing of the Savior. This is to be another strong motivation to godly living, a fact that is even more obvious in the Greek text. “As we wait” represents the translation of another adverbial participle that is dependent on the previous verb, “that we should live.” We could easily translate it,

we should live... by waiting expectantly for the happy fulfillment of our hope (literally, the blessed hope)...

The participle points us to one of the means by which we are to live in this present age, by living with a view to the return of Christ. Waiting for the blessed hope provides added incentives that enable us to live godly lives in this present age. (Titus 2:11-15 Godly Behavior)

Looking for the blessed hope - As someone has well said when it comes to belief in the Lord's return there are two kinds of Christians—gazers and goers. Paul is charging Titus to be a gazing goer, motivated to live in the light of the One Whom he is continually looking for.

Lehman Strauss rightly observes that...

The upward look for the coming again of the Lord Jesus is an effective counteraction for an unbalanced mind.

John Blanchard wrote that...

The certainty of the Second Coming of Christ should touch and tincture every part of our daily behavior.

William Gurnall said that...

Christ hath told us he will come, but not when, that we might never put off our clothes, or put out the candle.

Looking for (4327) (prosdechomai from pros = in compound Greek words implies motion or direction toward + dechomai [see word study] = a deliberate and ready reception) means to accept favorably, to receive one into intercourse/companionship, to give access to oneself or receive to oneself. 

To receive one coming from some place and so to welcome with friendliness (Ro 16:2, Phil 2:29).

To wait for with a sense of expectancy (Mark 15:43, Luke 2:25, 38, 12:36, 23:51, Acts 23:21, Titus 2:13, Jude 1:21)

The root verb dechomai means to accept deliberately and readily, receive kindly and so to take to oneself what is presented or brought by another. It means to welcome as a teacher, a friend, or a guest into one's house.  The word describes accepting persons with open arms, minds, and hearts, even going beyond normally expected gracious hospitality. The term was often used of welcoming honored guests and meeting their needs with special attention and kindness.

Prosdechomai is used of things future, in the sense of expecting and with the meaning of accepting. This verb is virtually always is found in the middle voice conveying reflexive action (action directed or turned back on self) which means that one receives to one’s self or gives another access to one’s self.

We need more men like G Campbell Morgan who said...

I never begin my work in the morning without thinking that perhaps he may interrupt my work and begin his own. I am not looking for death, I am looking for him.

Moulton-Milligan have this secular use of prosdechomai...

“I am waiting for the 450 drachma you have given to Radanus.” (Comment: We can probably all identify with this person's anticipation of  being repaid!)

Prosdechomai is used 15 times in the NAS (Mark; Luke 5x; Acts 3x; Romans; Philippians; Titus; Hebrews 2x; Jude) and is translated: accepted, 1; accepting, 1; cherish, 1; looking, 3; receive, 2; receives, 1; waiting, 5; waiting anxiously, 1;
 

Mark 15:43 Joseph of Arimathea came, a prominent member of the Council, who himself was waiting for the kingdom of God; and he gathered up courage and went in before Pilate, and asked for the body of Jesus.

Luke 2:25 And behold, there was a man in Jerusalem whose name was Simeon; and this man was righteous and devout, looking for the consolation of Israel; and the Holy Spirit was upon him.

Luke 2:38 And at that very moment she came up and began giving thanks to God, and continued to speak of Him to all those who were looking for the redemption of Jerusalem.

Luke 12:36 "And be like men who are waiting for their master when he returns from the wedding feast, so that they may immediately open the door to him when he comes and knocks.

Luke 15:2 And both the Pharisees and the scribes began to grumble, saying, "This man receives sinners and eats with them."

Luke 23:51 (he had not consented to their plan and action), a man from Arimathea, a city of the Jews, who was waiting for the kingdom of God;

Acts 23:21 "So do not listen to them, for more than forty of them are lying in wait for him who have bound themselves under a curse not to eat or drink until they slay him; and now they are ready and waiting for the promise from you."

Acts 24:15 having a hope in God, which these men cherish themselves, that there shall certainly be a resurrection of both the righteous and the wicked.

Romans 16:2 (note) that you receive her in the Lord in a manner worthy of the saints, and that you help her in whatever matter she may have need of you; for she herself has also been a helper of many, and of myself as well.

Philippians 2:29 (note) Therefore receive him in the Lord with all joy, and hold men like him in high regard;

Titus 2:13 (note) looking for the blessed hope and the appearing of the glory of our great God and Savior, Christ Jesus;

Hebrews 10:34 (note) For you showed sympathy to the prisoners, and accepted joyfully the seizure of your property, knowing that you have for yourselves a better possession and an abiding one.

Hebrews 11:35 (note) Women received back their dead by resurrection; and others were tortured, not accepting their release, in order that they might obtain a better resurrection;

Jude 1:21 keep yourselves in the love of God, waiting anxiously for the mercy of our Lord Jesus Christ to eternal life.

Thayer writes that prosdechomai...

as in Greek writings from Aeschylus and Herodotus down (meant) "to receive to oneself, to admit, to give access to oneself'... to admit one, receive into contact and companionship, Luke 15:2; to receive one (coming from some place), Romans 16:2; Philippians 2:29 (1 Chr. 12:18); to accept (not to reject) a thing offered: To reject, Hebrews 11:35; to admit (accept) hope, i.e., not to repudiate but to entertain, embrace, its substance, Acts 24:15... not to shun, to bear, an impending evil Hebrews 10:34.

(And) from Homer down (prosdechomai meant), to expect (look for, wait for): Luke 12:36;  Mark 15:43; Luke 2:25,38; 23:51 (Acts 23:21); Titus 2:13; Jude 1:21

If we are to be looking for Christ to return at any time, living in light of its imminency, such an "uplook outlook" should be a powerful incentive to spur us on to fight the good fight necessary for godly living and bold witnessing. Note the emphasis is that we are to be looking for the Christ and not for the Antichrist, for a one world government or for any other supernatural sign. Beloved, our Bridegroom's coming is imminent, and no prophetic event is required to precede His sure return (See related topics Imminency; Another discussion on imminency). Maranatha (Our Lord, come!).

Is that my mindset? Do my day to day choices
reflect the reality of an expectant attitude?

Expectant Looking
Is the "Antidote" for
Apathetic Living

Prosdechomai aptly describes the lifestyle and habitual attitude of the godly Jewish man named Simeon (who undoubtedly was a member of the Jewish remnant who had placed his faith in the Messiah):

And behold, there was a man in Jerusalem whose name was Simeon; (one of the believing Jewish remnant) and this man was righteous and devout, looking (prosdechomai  present tense) for the consolation of Israel (a synonym for the Redeemer Christ Jesus Who Himself would be the ultimate "consolation" of Israel); and the Holy Spirit was upon him. And it had been revealed to him by the Holy Spirit that he would not see death before he had seen the Lord's Christ.". (Luke 2:25-26)

Luke also uses prosdechomai  in his description of godly Anna writing

And there was a prophetess, Anna (one of the believing Jewish remnant) the daughter of Phanuel, of the tribe of Asher. She was advanced in years, having lived with a husband seven years after her marriage, and then as a widow to the age of eighty-four. And she never left the temple, serving night and day with fastings and prayers. And at that very moment she came up and began giving thanks to God, and continued to speak of Him to all those who were looking for (present tense - as their lifestyle in this present age which continually motivated them and pointed them toward the glorious future age, especially the Millennium) the redemption of Jerusalem (synonymous with the Redeemer Himself). (Luke 2:36-38)

Fanny Crosby (who was physically blind but had spiritual eyes of faith) caught the idea of expectant living in this line from Blessed Assurance (play hymn)

Perfect submission, all is at rest;
I in my Savior am happy and blest,
Watching and waiting, looking above,
Filled with His goodness, lost in His love.

Mark describes another Jew who was undoubtedly part of the saved Jewish remnant writing that

Joseph of Arimathea came, a prominent member of the Council, who himself was waiting for (prosdechomai  present tense - expectant waiting was his lifestyle which undoubtedly prompted godly living!) the kingdom of God and he gathered up courage and went in before Pilate, and asked for the body of Jesus. (Mark 15:43) (Comment: Notice how his future focused perspective emboldened his present actions, which is exactly what should happen in every believer's life...to the glory of God!)

As mentioned above, prosdechomai was used of receiving to one's self with a welcoming attitude:

And both the Pharisees and the scribes began to grumble, saying, "This man receives (to Himself with a welcoming attitude) sinners and eats with them." (Luke 15:2)

I commend to you our sister Phoebe, who is a servant of the church which is at Cenchrea that you receive (prosdechomai) her in the Lord in a manner worthy of the saints, and that you help her in whatever matter she may have need of you; for she herself has also been a helper of many, and of myself as well. (see note Romans 16:1; 16:2)

Paul, writing to the saints at Philippi concerning his sending them Epaphroditus, his brother and fellow worker and fellow soldier, who was also their messenger and minister to Paul's need, encouraged the Philippians...

Therefore receive (prosdechomai - conveys the picture of someone who is filled with the Spirit welcoming another person with open arms and heart!) him in the Lord with all joy, and hold men like him in high regard (see note Philippians 2:29)

Prosdechomai is used in a negative sense in Acts, where we read

So do not listen to them, for more than forty of them are lying in wait for him (to kill Paul) who have bound themselves under a curse not to eat or drink until they slay him; and now they are ready and waiting for the promise from you. (Acts 23:21)

In a positive use Luke records Paul's testimony of...

having a hope (click discussion of Biblical hope) in God, which these men cherish (prosdechomai present tense) themselves, that there shall certainly be a resurrection of both the righteous and the wicked. (Acts 24:15)

The writer of Hebrews explains that those having a sure future with God can even "welcome" present affliction encouraging his readers

For you showed sympathy to the prisoners, and accepted (prosdechomai) joyfully the seizure of your property, knowing that you have for yourselves a better possession and an abiding one. (see note Hebrews 10:34) (Comment: Notice how their "firm grip" on their future possession, prompted a "loose grip" on the temporal possessions of this present age which is passing away and along with its lusts).

Jude also associates this expectant attitude with living for God writing

keep (aorist imperative - command to guard, practice watchful care of) yourselves (take care of your business, not everyone else's! And do so by means of the two things just mentioned in context, building themselves up in their Christian lives and by praying in the Holy Spirit) in (in the sphere of His love - see to it that they stay within "the circle" of His love) the love of God, waiting anxiously (prosdechomai  present tense - this was to be their continual mindset) for the mercy of our Lord Jesus Christ to eternal life (which Wuest feels seems to point to that part of eternal life which will be given the saint at the Rapture = glorification)." (Jude 1:21)

Jesus used this verb in His exhortation to His disciples live life with an expectant attitude and to...

be like men who are waiting (prosdechomai  present tense) for their master when he returns from the wedding feast, so that they may immediately open the door to him when he comes and knocks. (Luke 12:36)

Prosdechomai is used 46 times in the Septuagint (LXX) (Ge 32:20; Ex 10:17; 22:11; 36:3; Lev. 26:43; Ruth 1:13; 1 Chr. 12:18; 2 Chr. 36:21; Est. 9:23, 27; Job 2:9; 29:23; 33:20; Ps. 6:9; 55:8; 104:11; Prov. 15:15; Isa. 28:10; 42:1; 45:4; 55:12; Ezek. 20:40f; 32:10; 43:27; Dan. 7:25; Hos. 8:13; Amos 5:22; Mic. 6:7; Mal. 1:8, 10, 13) with meanings generally similar to the NT uses.

Here is one use from Psalms...

The LORD has heard my supplication. The LORD receives (prosdechomai) - He welcomes it! In a sense He even looks expectantly for it!) (Psalm 6:9)  (Spurgeon says "Here is past experience used for future encouragement." See Spurgeon's complete note)

John explains that looking for Christ's appearing will affect your daily choices, writing...

Beloved, now we are children of God, and it has not appeared as yet what we shall be. We know that, when He appears, we shall be like Him, because we shall see Him just as He is.  everyone who has this hope fixed on Him purifies himself (motivated by love not fear...perfect love casts out all fear...perfect love would connote "perfect" as far as humanly possible, obedience.) just as He is pure." (1 John 3:2-3)

In a similar vein,  where Jesus' promise in the last chapter of the last book of the Bible should also motivate believers to look for Him and to live for Him...

Behold, I am coming quickly, and My reward is with Me, to render to every man according to what he has done. (see note Revelation 22:12)

J. C. Ryle correctly concludes that the...

Uncertainty about the date of the Lord's return is calculated to keep believers in an attitude of constant expectation and to preserve them from despondency.

Spurgeon adds that...

The fact that Jesus Christ is to come again is not a reason for star-gazing, but for working in the power of the Holy Ghost.

Looking at Titus 2:11-13 from another perspective, it is interesting to see how Paul uses this short but powerful section of Scripture to summarize the truth inherent in the Three Tenses of Salvation:
 

In short, God’s grace redeems us, reforms us and rewards us! Amazing grace! How sweet the sound that has saved, is saving and will save a wretch like me!

Reuben A. Torrey wrote that...

The imminent return of our Lord is the great Bible argument for a pure, unselfish, devoted, unworldly, active life of service.

Spurgeon writes that...

One work of the grace of God is to cause us to be “looking for that blessed hope of the glorious appearing of the great God and our Savior Jesus Christ.”

What is that “blessed hope?” Why, first, that when He comes we shall rise from the dead, if we have fallen asleep; and that, if we are alive and remain, we shall be changed at His appearing. (see notes beginning 1Thessalonians 4:13)

Our hope is that we shall be approved of Him and shall hear him say, “Well done, good and faithful servant.” This hope is not of debt, but of grace: though our Lord will give us a reward, it will not be according to the law of works.

We expect to be like Jesus when we shall see him as he is. When Jesus shines forth as the sun, “then shall the righteous shine forth as the sun in the kingdom of our Father.”

Our gain by godliness cannot be counted down into the palm of our hand. It lies in the glorious future (see note 1Timothy 4:8); and yet to faith it is so near that at this moment I almost hear the chariot of the Coming One. The Lord cometh, and in the coming of the Lord lies the great hope of the believer, his great stimulus to overcome evil, his incentive to perfect holiness in the fear of the Lord. Oh to be found blameless in the day of the manifestation of our Lord! God grant us this! Do you not see, brethren, how the discipline of the doctrine of grace runs towards the separating of us from sin, and the making us to live unto God? (From Spurgeon's sermon Two Appearings & the Discipline of Grace)

Billy Graham was right when he said that...

The subject of the second coming of Christ has never been popular to any but the true believer.

><>><>><>

After World War II there was a sign on the shore of New York harbor facing all incoming troop ships, which read:

WELCOME HOME.
WELL DONE.

When the Lord Jesus Christ appears in the air, He is going to “WELCOME HOME” every saint, for at that time He shall come to take us home to heaven. Our entrance into heaven is solely on the basis of our faith in His shed blood and death on the cross, and every believer shall receive the same “WELCOME HOME.” But, how many of us will receive His “WELL DONE,” and the “crown of righteousness”? (see note 2 Timothy 4:8)

THE BLESSED HOPE: ten makarian elpida: (Titus 1:2; 3:7; Acts 24:15; Ro 5:5; 8:24,25; 15:13; Col 1:5,23,27; 2 Th 2:16; Heb 6:18,19; 1 Pe 1:3; 1Jn 3:3)  (see Our Blessed Hope for detailed analysis of "hope")

Paul had earlier alluded to one aspect of the believer's hope writing that we are to live godly...

in (in the sphere of, circle of or atmosphere of) the hope (not a "hope I make it" mentality but absolute assurance that God will do good to me in the future) of eternal life, which God, who cannot lie, promised long ages ago (see note Titus 1:2)

He reiterates this truth in Titus 3 explaining that by grace through faith, believers are now...

justified by His grace (and) we might be made heirs according to the hope (absolute certainty) of eternal life. (see note Titus 3:7)

Blessed (3107) (makarios) (Click study of makarios) means spiritually “prosperous”, fully satisfied independent of the circumstances because of the amazing enabling grace in which we stand and the supernatural ministry of the indwelling  Holy Spirit (cp note Matthew 5:6). The sure hope we have of the return of our Bridegroom, the Lord Jesus, to catch up (and out of this present evil age) His Bride, the Church (see Rapture), is one that is prosperous, filled with richness and one that stabilizes our souls in this present world in which we live as aliens and strangers (we're just "passing through").

The second coming of Christ, including the first phrase or stage of that coming, the resurrection of those who died in Christ and the catching up (Rapture) of those believers still living when He comes, is the "blessed hope" of the Christian. The forgiveness of sins coupled with living a godly life eliminates all dread over the return of Christ and transforms the prospect into a blessed hope.

It is important to note that the KJV translates “blessed hope” and “appearing of the glory” as if they were two different entities, whereas the Greek construction requires that they be construed as one.

Looking for that blessed hope, and the glorious appearing of the great God and our Saviour Jesus Christ (KJV)

Granville Sharp’s rule says that when there are two nouns in the same case connected by and (kai), the first noun has the definite article (the = Greek word ten), and the second noun lacks the definite article, then the second noun refers to the same thing as the first noun and serves as a further description. Thus, the blessed hope is the appearing of the glory of our Lord.

Hope (1680) (elpis) (Click for in depth definition of elpis) is expectation or confidence and in the New Testament describes the believer's absolute certainty of future good. Hope is full assurance ("the full assurance of hope" Hebrews 6:11) and ultimately is found in the Person of Christ for as Paul wrote to Timothy "Christ Jesus (is) our hope" (1Timothy 1:1)
 

W. H. G. Thomas eloquently described the interrelationship of the great Christian triumphurate of faith, hope and love...

Faith rests on the past, love works in the present, and hope presses toward the future; or, faith looks backward and upward, love looks outward, and hope looks forward. These three constitute the true, complete Christian life and not one of them should be omitted or slighted.

We are only too apt to emphasize faith and love and forget hope but, inasmuch as hope is invariably connected with the coming of the Lord, that blessed hope (Titus 2:13), it is a vital part of our Christian life.

Faith accepts, hope expects; faith appropriates, hope anticipates; faith receives, hope realizes; faith is always and only concerned with the past and present, hope is always and only concerned with the future. We know that faith comes by hearing; we shall find that hope comes by experience. Faith is concerned with a person who promises, hope with the thing promised; and faith is the root of which hope is a fruit.

Zabriskie has an interesting thought writing that...

perhaps the reason why so few today look with favor upon the Blessed Hope is that perhaps they have rebelled at God’s lessons in grace and have reversed the determination of Moses: “Choosing rather to suffer affliction with the people of God, than to enjoy the pleasures of sin for a season” (see note Hebrews 11:25). Although ...God will not allow a child of His to sin lawlessly, yet often, after continual rebellion against His will, He will let the child have his own way for a season to prove to Him that God’s way is best. This action on God’s part may be seen in the case of the children of Israel. On one occasion, after they had rebelled continuously against God’s will for them, He sent to them the desires of their hearts but sent leanness to their souls. (KJV of Ps 106:15 And he gave them their request; but sent leanness into their soul.- Spurgeon's note) What a pathetic picture and yet how adequately this describes the spiritual lives of many Christians. (The Discipline of Grace, Bibliotheca Sacra 93:370. April, 1936. Page 178)

AND THE APPEARING OF THE GLORY: kai epiphaneian tes doxes: (Job 19:25-27; Isa 25:9; Mt 16:27; 25:31; 26:64; Mk 8:38; 14:62; 1Ti 6:13,14; Heb 9:28; 2Co 4:4,6; Col 3:4; 1Pe 1:7; 1Jn 3:2; Rev1:7)

Chrysostom rightly said that...

In the first advent God veiled his divinity to prove the faithful; in the second advent he will manifest his glory to reward their faith.

Appearing (2015) (epiphaneia from the verb epiphaino [used in Titus 2:11, 3:4 click word study on epiphaino] in turn from epí = over, upon or to + phaíno = to shine) (See word study on epiphaneia) is literally "a shining upon" and from its secular used conveys the thought of an event which is sudden and unexpected. Secular Greek writings used this word group to describe the appearance of pagan "gods" but in this verse Paul is saying there is a glorious second coming of of the one living and true God, Jesus Christ.

Epiphaneia is a solely used by Paul, first to describe the counterfeit appearance of the Antichrist ("the cursed hope", "the false hope") Paul informing the Thessalonian saints that the

lawless one (the Antichrist) will be
