Colossians 1:9

we also--on our part. heard it-- (Col 1:4). pray--Here he states what in particular he prays for; as in Col 1:3 he stated generally the fact of his praying for them. to desire--"to make request." might be filled--rather, "may be filled"; a verb, often found in this Epistle (Col 4:12, Col 4:17). knowledge--Greek, "full and accurate knowledge." Akin to the Greek for "knew" (see on Col 1:6). of his will--as to how ye ought to walk (Eph 5:17); as well as chiefly that "mystery of His will, according to His good pleasure which He purposed in Himself; that in the fulness of times He might gather together in one all things in Christ" (Eph 1:9-10); God's "will," whereby He eternally purposed to reconcile to Himself, and save men by Christ, not by angels, as the false teachers in some degree taught (Col 2:18) [ESTIUS]. There seems to have been a want of knowledge among the Colossians; notwithstanding their general excellencies; hence he so often dwells on this subject (Col 1:28; Col 2:2-3; Col 3:10, Col 3:13; Col 4:5-6). On the contrary he less extols wisdom to the Corinthians, who were puffed up with the conceit of knowledge. wisdom--often mentioned in this Epistle, as opposed to the (false) "philosophy" and "show of wisdom" (Col 2:8, Col 2:23; compare Eph 1:8). understanding--sagacity to discern what on each occasion is suited to the place and the time; its seat is "the understanding" or intellect; wisdom is more general and has its seat in the whole compass of the faculties of the soul [BENGEL]. "Wouldst thou know that the matters in the word of Christ are real things? Then never read them for mere knowledge sake" [Quoted by GAUSSEN.] Knowledge is desirable only when seasoned by "spiritual understanding."

The apostle proceeds in these verses to pray for them. He heard that they were good, and he prayed that they might be better. He was constant in this prayer: We do not cease to pray for you. It may be he could hear of them but seldom, but he constantly prayed for them. - And desire that you may be filled with the knowledge, etc. Observe what it is that he begs of God for them, I. That they might be knowing intelligent Christians: filled with the knowledge of his will, in all wisdom and spiritual understanding. Observe, 1. The knowledge of our duty is the best knowledge. A mere empty notion of the greatest truths is insignificant. Our knowledge of the will of God must be always practical: we must know it, in order to do it. 2. Our knowledge is then a blessing indeed when it is in wisdom, when we know how to apply our general knowledge to our particular occasions, and to suit it to all emergencies. 3. Christians should endeavour to be filled with knowledge; not only to know the will of God, but to know more of it, and to increase in the knowledge of God (as it is Col 1:10), and to grow in grace, and in the knowledge of our Lord and Saviour, Pe2 3:18. II. That their conversation might be good. Good knowledge without a good life will not profit. Our understanding is then a spiritual understanding when we exemplify it in our way of living: That you may walk worthy of the Lord unto all pleasing (Col 1:10), that is, as becomes the relation we stand in to him and the profession we make of him. The agreeableness of our conversation to our religion is pleasing to God as well as to good men. We walk unto all well-pleasing when we walk in all things according to the will of God. Being fruitful in every good work. This is what we should aim at. Good words will not do without good wo…

1:9-10 Paul prays that God would grant his readers deeper understanding of the Good News and its full expression in their lives. Spiritual growth yields a clearer and deeper comprehension of Christian truth and conduct that pleases the Lord, through which a believer will have the endurance and patience to stand firm against evil (1:11).
