(9-12) From thanksgiving St. Paul passes, as always, to pray for them. The prayer is for their full and perfect knowledge of God's will; but this is emphatically connected with practical "walking" in that will, first by fruitfulness in good work, next by showing themselves strong in Christ to endure sufferings, lastly by thankful acceptance of God's call to inheritance among the saints in light. There is a hearty recognition of the blessing of knowledge (on which the incipient Gnosticism of the day was so eloquent); but it is to be tried by the three tests of practical goodness, patience, and thankful humility.

(9) Do not cease to pray for you.--Comp. Ephesians 1:16. "To pray" (see Ephesians 6:18; Philippians 4:6) is the general word for "to worship"; "to desire" indicates prayer, properly so called, asking from God what is requisite and necessary for ourselves or for others.

The knowledge of his will.--The "knowledge" here spoken of is the "full knowledge," to be attained in measure here, to be made perfect in heaven. See 1Corinthians 13:12, "Now I know in part; but then shall I know (perfectly) even as I am known." On this word, especially frequent in the Epistles of the captivity, see Note on Ephesians 1:17. It should be noted that the knowledge here prayed for is "the knowledge of God's will"--not speculation as to the nature of God, or as to emanations from Deity, or even as to the reasons of God's mysterious counsels, but knowledge of what actually is His will, both in the dispensation which is to be accepted in faith, and in the commandments to be obeyed in love. So St. Paul (in 1Timothy 1:4-5) contrasts with the "fables and endless genealogies" of Gnostic speculation, "the end of the commandment," "charity out of a pure heart and a good conscience, and faith unfeigned."

In all wisdom and spiritual understanding.--This "knowledge of God's will" is man's "wisdom." For "wisdom" is the knowledge of the true end of life; which is (as the Book of Ecclesiastes so tragically shows) vainly sought, if contemplated apart from God's will, but found (see Ecclesiastes 12:13; Job 28:28; Proverbs 1:7) in the "fear of the Lord" and the "keeping of His commandments." (On the relation of the supreme gift of wisdom to lesser cognate gifts, see Note on Ephesians 1:8.) "Understanding" here is properly the faculty of spiritual insight or judgment, the speculative exercise of wisdom, as the "prudence" of Ephesians 1:8 is the practical. Hence St. Paul subjoins the practical element at once in the next verse.

Verse 9. - For this cause we also (Ephesians 1:15-17; 1 Thessalonians 3:6-13). Timothy and I, in return for your love to us (ver. 8) and in response to this good news about you (vers. 4-6). From the day that we heard (it); an echo of "from the day that ye heard it" (ver. 6). Do not cease praying for you, and making request. The former is a general expression (ver. 3), the latter points to some special matter of petition to follow. This second verb St. Paul only uses elsewhere of prayer to God in Ephesians 3:13, 20 (see Trench's 'Synonyms' on αἱτέω, αἵτημα). That ye may be filled with (or, made complete in) the knowledge of his will (Colossians 2:10; Colossians 4:12; Ephesians 3:18, 19; Romans 12:2; Hebrews 13:21). On "knowledge" (ἐπίγνωσις), see note. to ver. 6, and Lightfoot's note here. "With the knowledge" represents the Greek accusative of specification (as in Philippians 1:11, where see Ellicott); and the verb πληρωθῆτε (comp. note on pleroma, ver. 19), as in Colossians 2:10 and Colossians 1:25, denotes "fulfilled" or "made complete," rather than "made full" - "made complete as to the full knowledge," etc. "His will" ("God's will," ver. 1; Colossians 4:12) need not be limited to the original purpose of salvation (Ephesians 1:9), or to his moral requirements respecting Christian believers (ver. 10; so Meyer), but includes "the whole counsel of God" (Acts 20:27) made known to us in Christ (vers. 26, 27). In all spiritual wisdom and understanding (Colossians 2:2; Ephesians 5:17; Philippians 1:9; 1 Corinthians 14:20). Wisdom, in its highest sense, is the sum of personal excellence as belonging to the mind; it implies a vital knowledge of Divine truth, forming the sentiments and determining the will as it possesses the reason, Hence the word occurs in a great variety of connections: Wisdom and knowledge (Colossians 2:3), "and prudence" (Ephesians 1:8), etc. For this Church the apostle asks specially the gift of understanding or comprehension, (comp. Colossians 2:2; only in Ephesians 3:4 and 2 Timothy 2:7 besides, in St. Paul; 1 Corinthians 1:19 from LXX), the power of putting things together (σύν(εσις), of discerning the relations of different truths, the logical bearing and consequences of one's principles. For the errors invading Colossae were of a Gnostic type, mystic at once and rationalistic; against which a clear and well-informed understanding was the best protection (comp. notes on "truth," in vers. 5, 6; also Colossians 2:4, 8, 18, 23; Ephesians 4:13, 14). This "wisdom and understanding" are "spiritual," as inspired by the Divine Spirit (comp. the use of "spirit," "spiritual," in 1 Corinthians 12:1-11; Galatians 6:1 and Gal 5:16, 25; Ephesians 1:17; Ephesians 3:16-19), and opposed to all "wisdom of the flesh," the unrenewed nature of man (Colossians 2:18; 1 Corinthians 2:4-6, 13-15; James 3:15).

1:9-14 The apostle was constant in prayer, that the believers might be filled with the knowledge of God's will, in all wisdom. Good words will not do without good works. He who undertakes to give strength to his people, is a God of power, and of glorious power. The blessed Spirit is the author of this. In praying for spiritual strength, we are not straitened, or confined in the promises, and should not be so in our hopes and desires. The grace of God in the hearts of believers is the power of God; and there is glory in this power. The special use of this strength was for sufferings. There is work to be done, even when we are suffering. Amidst all their trials they gave thanks to the Father of our Lord Jesus, whose special grace fitted them to partake of the inheritance provided for the saints. To bring about this change, those were made willing subjects of Christ, who were slaves of Satan. All who are designed for heaven hereafter, are prepared for heaven now. Those who have the inheritance of sons, have the education of sons, and the disposition of sons. By faith in Christ they enjoyed this redemption, as the purchase of his atoning blood, whereby forgiveness of sins, and all other spiritual blessings were bestowed. Surely then we shall deem it a favour to be delivered from Satan's kingdom and brought into that of Christ, knowing that all trials will soon end, and that every believer will be found among those who come out of great tribulation.For this cause we also,.... Not merely for their love to the apostle, and the rest that were with him; which sense is too much contracted, and carries some appearance of meanness and selfishness; but because of their faith in Christ, their love to all the saints, and the good hope they had of eternal happiness; and because they had heard the Gospel, and truly knew it, and sincerely professed it: therefore,

since the day we heard it, do not cease to pray for you, and to desire; which shows that the apostles prayed without ceasing; not that they were every moment praying, without intermission, but that they were frequent and constant every day at the throne of grace; and as often as they were there, they were mindful of these Colossians, even ever since they heard of their reception of the Gospel, of their profession of it, and of the fruit it brought forth in them; and in their petitions "prayed" and "desired", earnestly and importunately entreated God on their behalf:

that ye might he filled with the knowledge of his will; the will "of God", as the Syriac version reads it, by which is meant, not the secret will of God, according to the counsel of which he does all things in nature, providence, and grace, but his revealed will; and that either as it is signified in the law, which declares the good, and perfect, and acceptable will of God, relating to what he would have done, or avoided by his creatures; or rather, as it is exhibited in the Gospel, which contains the will of God respecting the salvation of his chosen ones; as that it is his will that Christ should obtain eternal redemption for them, to do which he voluntarily substituted himself in their room, came into this world, and has accomplished it; and that all those that are redeemed by Christ should be regenerated by the Spirit; and that whoever sees the Son, and believes in him, should not perish, but have everlasting life; as also, that all those whom he has chosen in Christ, and given to him, and he has redeemed by his blood, and who are sanctified by his Spirit, none of them should be lost, but that they should be all saved with an everlasting salvation. Now the apostle does, not pray that they might have a "knowledge" of this will of God, for some knowledge of it they had already; they had heard of the hope laid up in heaven, in the truth of the word of the Gospel; they had not only had the external, revelation, and had heard the Gospel outwardly preached, but they had known truly the grace of God; and therefore what he asks for is, that they might be "filled" with the knowledge of it; which supposes that they had knowledge, but it was not full and complete; it was imperfect, as is the knowledge of the best of saints in this life; and that they might have a larger measure of it, and such a fulness of it as they were capable of in the present state, and not such an one as the saints will have in heaven, when they shall know even as they are known. He adds,

in all wisdom and spiritual understanding; his meaning is, that they might be led into all the wisdom of God, which is so largely displayed in the revelation of his will concerning the salvation of his people, which is made in the Gospel; which is the manifold wisdom of God, wherein he has abounded in all wisdom and prudence; and contains such a scheme of things, so wisely contrived and formed, that angels desire to look into it; and that they might have a "spiritual understanding" of the mysteries of grace, without which they cannot be discerned to spiritual advantage, nor indeed without the spirit of wisdom and revelation in the knowledge of them: and the Ethiopic version renders it, by "the prudence of the Holy Ghost": who searches the deep things of God, and reveals them to the saints, and improves and increases their spiritual and experimental knowledge of them, which is what is here intended.
