Colossians 1:12

Here is a summary of the doctrine of the gospel concerning the great work of our redemption by Christ. It comes in here not as the matter of a sermon, but as the matter of a thanksgiving; for our salvation by Christ furnishes us with abundant matter of thanksgiving in every view of it: Giving thanks unto the Father, Col 1:12. He does not discourse of the work of redemption in the natural order of it; for then he would speak of the purchase of it first, and afterwards of the application of it. But here he inverts the order, because, in our sense and feeling of it, the application goes before the purchase. We first find the benefits of redemption in our hearts, and then are led by those streams to the original and fountain-head. The order and connection of the apostle's discourse may be considered in the following manner: - I. He speaks concerning the operations of the Spirit of grace upon us. We must give thanks for them, because by these we are qualified for an interest in the mediation of the Son: Giving thanks to the Father, etc., Col 1:12, Col 1:13. It is spoken of as the work of the Father, because the Spirit of grace is the Spirit of the Father, and the Father works in us by his Spirit. Those in whom the work of grace is wrought must give thanks unto the Father.

You "giving thanks unto the Father." See on Col 1:10; this clause is connected with "that ye may be filled" (Col 1:9), and "that ye may walk" (Col 1:10). The connection is not, "We do not cease to pray for you (Col 1:9) giving thanks." unto the Father--of Jesus Christ, and so our Father by adoption (Gal 3:26; Gal 4:4-6). which hath made us meet--Greek, "who made us meet." Not "is making us meet" by progressive growth in holiness; but once for all made us meet. It is not primarily the Spirit's work that is meant here, as the text is often used; but the Father's work in putting us by adoption, once for all, in a new standing, namely, that of children. The believers meant here were in different stages of progressive sanctification; but in respect to the meetness specified here, they all alike had it from the Father, in Christ His Son, being "complete in Him" (Col 2:10). Compare Joh 17:17; Jde 1:1, "sanctified by God the Father"; Co1 1:30. Still, secondarily, this once-for-all meetness contains in it the germ of sanctification, afterwards developed progressively in the life by the Father's Spirit in the believer. The Christian life of heavenliness is the first stage of heaven itself. There must, and will be, a personal meetness for heaven, where there is a judicial meetness. to be partakers, &c.--Greek, "for the (or 'our') portion of the inheritance (Act 20:32; Act 26:18; Eph 1:11) of the saints in light.
