Colossians 1:11 strengthened (PPPMPN) with all power according to His glorious might, for the attaining of all steadfastness and patience; joyously  (NASB: Lockman)

STRENGTHENED WITH ALL POWER: en pase dunamei dunamoumenoi (PPPMPN): (Isa 45:24 Acts1:8 Ro15:13 2Co 4:7 2Co 12:9 Eph 3:16 6:10 Php 4:13)

"Full of strength in the measure of the great power of his glory," (BBE),
"that you may be invigorated and strengthened with all power according to the might of His glory" (Amp),
"May you be made strong with all the strength which comes from his glorious power, so that you may be able to endure everything with patience." (TEV)
"being empowered with all power" (ALT)

Strengthened (dunamoo) means to be enabled and speaks of an inherent power which gives one the ability to do something. The present tense indicates that believers are to be continuously strengthened, the passive voice indicating that the strengthening comes from without, from an outside Source (God) (Colossians 3:4). That power is available to the believer who is filled with the knowledge of God’s Word. God is not like a booster rocket giving believers an initial boost of power and then leaving them to fly on their own. Spiritual growth and maturity can come only as we yield to God’s word and permit Him to do His work in and through us.

Although dunamoo is used only here in the NT, the similar verb endunamoo is used in several instructive circumstances. For example, Paul writes to the Ephesians saints their need to "be strong (endunamoo - here a command to let yourself continually be strengthened) in the Lord and in the strength of His might." (Eph 6:10). From jail he writes his beloved Philippian church "I can do all things through Him who strengthens (endunamoo - present tense = continuous action) me." (Phi 4:13) Paul seeking to encourage Timothy for the difficult task before him wrote "I thank Christ Jesus our Lord, Who has strengthened me, because He considered me faithful, putting me into service." (1Ti 1:12)

All power describes an all sufficient source for all the trials of life, all the time.

As I obey, walking in the revealed knowledge (filled with the knowledge) of His will with all spiritual wisdom and understanding, I am continually being strengthened to bear up under whatever problem people or problem circumstances God allows into my life. In some languages one would translate this section as being “strong in your spirits” or “strong in your hearts,” for this is internal, moral strength and not physical strength.

Wiersbe makes the important point that

"the emphasis in Paul's prayer is on Christian character: patience, long-suffering, joyfulness, and thanksgiving. The inner victories of the soul are just as great, if not greater, than the public victories recorded in the annals of history. For David to control his temper when he was being maligned by Shimei was a greater victory than his slaying of Goliath (2Sa16:5-13). “He who is slow to anger is better than the mighty, and he who rules his spirit, than he who captures a city” (Pr16:32).

Matthew Henry comments that Paul prays that the saints may be

"fortified against the temptations of Satan and furnished for all their duty. It is a great comfort to us that he who undertakes to give strength to his people is a God of power and of glorious power. Where there is spiritual life there is still need of spiritual strength, strength for all the actions of the spiritual life. To be strengthened is to be furnished by the grace of God for every good work, and fortified by that grace against every evil one: it is to be enabled to do our duty, and still to hold fast our integrity. The blessed Spirit is the author of this strength; for we are strengthened with might by his Spirit in the inward man, Eph 3:16. The word of God is the means of it, by which he conveys it; and it must be fetched in by prayer. It was in answer to earnest prayer that the apostle obtained sufficient grace."

ACCORDING TO HIS GLORIOUS MIGHT: kata to kratos tes doxes autou:

According to (kata) means that the equipping with power is proportional not simply to the recipient’s need, but to the inexhaustible divine supply. Adam Clarke adds that it is "According to that sufficiency of strength which may be expected from him who has all power both in the heavens and in the earth."

Kratos = perfect strength or strength in action and in the NT it is applied to God 11/12x. Here God's might is accompanied by glory. Kratos refers to strength regarded as abundantly effective in relation to an end to be gained or dominion to be exercised and to overcome what stands in the way. It refers to the inherent strength which displays itself in the rule over others  Kratos denotes presence and significance of force or strength rather than its exercise. Kratos is “power in the sense of dominion” and thus stresses sovereign power or supreme authority.

His glorious might indicates that this strengthening is not by any human means, but by the power of God. There is a manifestation of power in the spirit with which Christians are enabled to bear up under trials, which shows that it is not of human origin and it is the power which God gives in the day of trial.  Here God's might is accompanied by glory (Shekinah).

FOR THE ATTAINING OF ALL STEADFASTNESS: eis pasan hupomonen: (note one can become confused when trying to understand "steadfastness" and "patience" because the same English word is used in many translations for both Greek words. Thus you cannot simply look up all the uses of "patience" but you need to utilize a Greek study tool to help you determine which Greek word is being translated). " so that you might patiently endure everything with joy" (ISV)

Steadfastness (NASB also translates it as endurance, patient enduring and most often as perseverance) is the Greek word hupomone (hupo = under + meno = abide) which has to do more with one's response to difficult circumstances than with difficult people. Hupomone is is “endurance when circumstances are difficult” and is manifest by "remaining under" difficulties without succumbing.

Steadfastness (perseverance) is an important characteristic of the maturing Christian growing best in the field of affliction, as James writes --"the testing of your faith produces endurance (hupomone)" (Ja 1:3-4)  is also associated with self-control in (2Pe 1:6). If we do not learn to be patient, we are not likely to learn anything else. As believers, can even "exult in our tribulations, knowing that tribulation brings about perseverance (hupomone) and perseverance, proven character; and proven character, hope” (Ro 5:3-4).  So despite the trial, the man who perseveres does not lose heart. James reminds his readers of Job "Behold, we count those blessed who endured. (verb form hupomeno) You have heard of the endurance (hupomone) of Job and have seen the outcome of the Lord's dealings, that the Lord is full of compassion and is merciful." (Ja 5:11)

As the former president of Wheaton College, Dr. Edman, would often remind the students “It is always too soon to quit.” Ponder that statement and the blessing of bearing up under when you find yourself in the midst of trying circumstances.

Henry comments

When we bear our troubles well, though ever so many, and the circumstances of them ever so aggravating, then we bear them with all patience (steadfastness)....All patience includes all the kinds of it; not only bearing patience, but waiting patience.

The UBS Handbook notes that...

In some languages, patience is best expressed as a negation of some negative quality, for example, “enduring without complaining” or “enduring and not being resentful.”   (The United Bible Societies' New Testament Handbook Series or Logos)

Do not think that steadfastness is complacency but in contrast is endurance in action. It is not the Christian sitting in a rocking chair, waiting for God to do something. It is the soldier on the battlefield, keeping on when the going is tough. It is the runner on the race track, refusing to stop because he wants to win the race. Too many Christians have a tendency to back away or even to quit when circumstances become difficult.    Spurgeon said ''By perseverance the snail reached the ark.'' It is not talent or training that guarantees victory: it is perseverance.

AND PATIENCE: kai makrothumian:

Patience (long-suffering -long and patient endurance of offense) makrothumia (makros = long + thumos = temper, a tumultuous welling up of the whole spirit; a mighty emotion which seizes and moves the whole inner man) (click for in depth study of makrothumia) is manifesting a long endurance that does not retaliate.  Makrothumia is characterized by an emotional calm in face of provocation or misfortune. It is a long holding out of the mind before it gives room to passion and so refers to the self-restraint which does not hastily revenge a wrong and expresses itself in patience without complaint or irritation in the face of injustice or unpleasant circumstances. As Trench summarizes, makrothumia expresses patience in respect to persons, hupomone in respect to things or circumstances. While both graces are used to describe men, only makrothumia is used of God. Men may tempt and provoke Him, and He may and does display an infinite makrothumia in regard of them (e g, Ro 2:4)

Patience (makrothumia) or long-suffering is a fruit of the Spirit (Ga5:22) and is an important trait for us to exhibit and practice and so the writer of Hebrews exhorts believers to not to be "sluggish but (be) imitators of those who through faith and patience inherit the promises (and he gives the example of God promising to bless and multiply Abraham)" (Heb 6:12-14)

Paul later exhorts the Colossians to "put on a heart of compassion, kindness, humility, gentleness and patience (makrothumia)..." (Colossians 3:12)

Paul commanded young Timothy to "preach the word; be ready in season and out of season; reprove, rebuke, exhort, with great patience (makrothumia) and instruction." (2Ti 4:2), a situation that would definitely call for having a "long temper" with difficult people. The short-tempered person speaks and acts impulsively and lacks self-control. When a person is longsuffering, he can put up with provoking people or circumstances without retaliating. It is good to be able to get angry, for this is a sign of holy character. But it is wrong to get angry quickly at the wrong things and for the wrong reasons.

It is amazing how people can patiently endure trying circumstances, only to lose their tempers with a friend or loved one. Moses was patient during the contest with Pharaoh in Egypt. But he lost his temper with his own people and, as a result, forfeited his right to enter the Promised Land (Nu20). “Like a city that is broken into and without walls is a man who has no control over his spirit” (Pr25:28).

JOYOUSLY: Meta charas:

Joyously is literally "with joy" and as Expositors says; “It (joyfulness) forms a very necessary addition, for the peculiar danger of the exercise of those qualities is that it tends to produce a certain gloominess or sourness of disposition. The remedy is that the Christian should be so filled with joy that he is able to meet all his trials with a buoyant sense of mastery.” In a number of languages, joy is expressed figuratively as “with a happy heart” or “with dancing in one’s heart” or “with a heart that sings.”

As Henry reminds us

to have joy as well as patience in the troubles of life...we could never do by any strength of our own, but as we are strengthened by the grace of God.

God’s power is evidenced in our lives not only in our patience and long-suffering, but also in our joyfulness. When circumstances are difficult, we should exhibit joyful patience; and when people are hard to live with, we should reveal joyful long-suffering. There is a kind of patience that “endures but does not enjoy.” Paul prayed that the Colossian Christians might experience joyful patience and long-suffering.

Colossians 1:12 giving thanks (PAPMPN) to the Father , Who has qualified (AAPMSD) us to share in the inheritance  of the saints in light.

The Colossian epistle is filled with thanks, thankfulness and thanksgiving (click here). Paul himself gave thanks for the Colossian church (Col. 1:3), and then prayed that they themselves might grow in their giving of thanks to God (Col. 1:12). He commanded believers as those who chosen of God, holy and beloved, to continually be thankful (Col 3:15) and to "let the word of Christ richly dwell within...singing with thankfulness in your hearts to God." (Col 3:16) In case he missed anything Paul exhorted the Colossians that in "whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks through Him to God the Father." (Col 3:17) Finally Paul emphasized the importance of thankfulness in prayer instructing them "Devote yourselves to prayer, keeping alert in it with an attitude of thanksgiving" (Col. 4:2).

Giving thanks (present tense = continually, as a lifestyle, habitually, at all times, in all situations!) (eucharisteo from eu = well, good + charizomai = grant out of kindness, this Greek word in turn from charis = grace) Only as a believer is filled with (controlled by) and empowered by the Holy Spirit will he or she continually be "giving thanks" to their Father (Eph 5:18-20).  Only those who are surrendered to the Spirit's control (click for discussion of "filled") can really be thankful in times of suffering, disappointment, or bereavement. This exhortation thus proves our need of the Spirit of God, because in our own strength we could never fulfill this. Keep in mind that Paul was a prisoner when he wrote these words, and yet he was thankful to God  (Col 1:3).

Warren Wiersbe gives some excellent practical advice writing that

"When a Christian finds himself in a difficult situation, he should immediately give thanks to the Father, in the name of Jesus Christ, by the power of the Spirit, to keep his heart from complaining and fretting. The devil moves in when a Christian starts to complain, but thanksgiving in the Spirit defeats the devil and glorifies the Lord."

When we become ungrateful, we begin to complain and look at people and circumstances with a critical spirit.  Someone has written "Don't complain about thorns among the roses! Be grateful for roses among the thorns!" Paul said it even better exhorting us to “In everything give thanks; for this is God's will for you in Christ Jesus” (1Th 5:18).  Note that Paul is not exhorting us to give thanks for everything but in everything. For example, Job could give thanks even after losing all his possessions and even his children (Job 1:21-22). Empowered by the Spirit we can all should all seek an attitude like Habakkuk had declaring "Though the fig tree should not blossom, and there be no fruit on the vines, though the yield of the olive should fail, and the fields produce no food, though the flock should be cut off from the fold, and there be no cattle in the stalls, yet I will exult in the LORD, I will rejoice in the God of my salvation." (Hab 3:17, 18)  This kind of thankfulness is God's will.

As you noted the Greek word for "giving thanks" is eucharisteo which is from to the root charizomzai which in turn is derived from charis or grace.  The point is that for those who have experienced the grace of God, now have the power of God to be grateful for what God allows into our life. Thank and think also come from the same root word. If we would think more about all we have to be thankful for, we would all be a lot more likely to thank more. In context as we think about  the fact that the Father has "qualified us" for entry into His presence eternally,  that truth should motivate us to an attitude of continual gratitude.

The thankful saint is one who is conscious of benefits they have received. The Merriam Webster Thesaurus has the following antonyms  for "thankful" -- unappreciative, ungrateful, self-centered; careless, thoughtless; unappreciative, ungrateful. The tragic story is told about a young a ministerial student, Edward Spencer, who personally saved 17 person on September 8, 1860, when a passenger boat floundered on the lake. The exertion permanently damaged Spencer's health and he was unable to continue his pursuit of the ministry. At his death some years later, it was noted that not one of the 17 persons he had saved ever came to thank him. We all think "How horrible!" but how many times have we all forgotten to "in everything give thanks" to our heavenly Father for so great a salvation! Unfortunately we are all have a tendency to be eager to ask but slow to appreciate our heavenly Father continual benevolence.

MacArthur comments  that

Father emphasizes the personal, relational aspect of our union with God. Before our salvation, God was our Judge. We stood condemned before Him for violating His holy, just laws. But when, through the grace of God, we placed our faith in Christ, God ceased being our sentencing Judge and became our gracious Father.

WHO HAS QUALIFIED US:to hikanosanti (AAPMSD) humas: (Ro 8:29-30 2 Co3:5-6 2Co 5:5 Titus 2:14)

KJV translates it "made us meet" (see hymn #3 below - click on the hymn for all 3 convicting stanzas)

made us fit (Darby)

the Father Who prepared and fitted us all (Lightfoot),

Who has qualified and made us fit (Amplified),

made you competent (Bible Knowledge Commentary)

We should continually give thanks to the Father Himself because He qualified  believers making them competent to partake of the inheritance of the saints by placing them in Christ, in Whom they enjoy a standing which makes them the objects of God’s grace, today and forevermore! That calls for thanksgiving.

Qualified (hikanoo) (aorist tense = effective action at a point in time, past completed action ~ the act of making them fit or qualified = that moment when God saved us) means to make fit, adequate, sufficient for a specific requirement or to render competent or worthy. By the past completed act (aorist tense) of Jesus crucifixion and our co-crucifixion with Him, believers are "worthy" because  "worthy is the Lamb Who was slain" and they are now in Christ. When an individual by faith receives what was prepared from the foundation of the world, they are made sufficient in Christ and thus qualified to enter the Holy of Holies by the blood of the Lamb, qualified to receive full possession of their inheritance which will be realized in the future. 

Hikanoo is in the passive voice which emphasizes that we received the effect of the qualifying from God -- He made us fit for future glory in the Beloved, His Son. There is simply no other way to share in the inheritance unless God qualifies us. In contrast the Gnostics taught you could get enough knowledge to get to heaven and so were like every other false religious system which when distilled to the essence all teach salvation by works. Paul is clearly stating that no man can qualify himself no matter how much "gnosis" he acquires! God is the only "Qualifier". The sense is, he has conferred on us grace sufficient to make it proper that we should partake of the blessings of his kingdom.  This truth should make us humble and thankful, for there is simply nothing we could have done to make ourselves meet, fit, adequate, qualified or worthy to enter into the kingdom of God.

O I am my Beloved’s and my Beloved’s mine!
He brings a poor vile sinner into His “house of wine.”
I stand upon His merit—I know no other stand,
Not even where glory dwelleth in Immanuel’s land.
-- Anne R. Cousin  (Play hymn)

Man’s work faileth, Christ’s availeth;

Oh, to be nothing, nothing,
Only to lie at His feet,
A broken and emptied vessel,
For the Master’s use made meet.
Emptied that He might fill me
As forth to His service I go;
Broken, that so unhindered,
His life through me might show.
-- Georgiana Taylor. (Play hymn)

Come, Lord, when grace hath made me meet
Thy blessed face to see;
For if Thy work on earth be sweet
What will Thy glory be!
-- Richard Baxter (Play hymn)

Paul in explaining why and how he was competent for the ministry he was carrying out in Corinth used 3 forms of hikanoo (noun, verb and adjective) writing that "Not that we are adequate (adjective = hikanos) in ourselves to consider anything as coming from ourselves, but our adequacy (noun = hikanotes) is from God Who also made us adequate (verb = hikanoo) as servants of a new covenant, not of the letter, but of the Spirit; for the letter kills, but the Spirit gives life." (2Cor 3:5-6).

William MacDonald eloquently sums up the gist of qualified writing "When God saves someone, He instantly bestows on that person fitness for heaven. That fitness is Christ. Nothing can improve on that. Not even a long life of obedience and service here on earth makes a person more fit for heaven than he was the day he was saved. Our title to glory is found in His blood."

In a passage with a parallel thought Paul writes "Now He Who prepared us for this very purpose (what purpose? from previous verse = "what is mortal may be swallowed up by life" = glorified immortal bodies) is God, Who gave to us the Spirit as a pledge." (2Cor 5:5)

TO SHARE IN THE INHERITANCE: eis ten merida tou klerou: (1Pe 1:3-5) (See summary of inheritance from Baker's Evangelical Dictionary below or Click here for ISBE article)  "for the portion of the lot" (Literal)

"Share" (meris) refers to a portion of a whole that has been divided. So the Greek reads more literally " for the portion of the lot", that is we each receive our own individual allotment or portion of the total inheritance.  In the OT, God’s people had an earthly inheritance, the land of Canaan, and each tribe received its portion of the lot. Christians have a spiritual inheritance in Christ (see Hymn below "Be Thou My Vision"). Crossing the Jordan to Canaan is unfortunately often portrayed as a picture of heaven but this is not an accurate portrayal for there will be no battles or defeats in heaven. More accurately, Canaan can be considered a picture of our present inheritance in kingdom of God's beloved Son, Jesus Christ.
