17 And he is before all, and all things subsist together by him. 18 And he is the head of the body, the assembly; who is [the] beginning, firstborn from among the dead, that he might have the first place in all things: 19 for in him all the fulness [of the Godhead] was pleased to dwell, 20 and by him to reconcile all things to itself, having made peace by the blood of his cross—by him, whether the things on the earth or the things in the heavens.

Paul's Ministry to the Church

21 And you, who once were alienated and enemies in mind by wicked works, yet now has it reconciled 22 in the body of his flesh through death; to present you holy and unblamable and irreproachable before it, 23 if indeed ye abide in the faith founded and firm, and not moved away from the hope of the glad tidings, which ye have heard, which have been proclaimed in the whole creation which [is] under heaven, of which I Paul became minister. 24 Now, I rejoice in sufferings for you, and I fill up that which is behind of the tribulations of Christ in my flesh, for his body, which is the assembly; 25 of which I became minister, according to the dispensation of God which [is] given me towards you to complete the word of God, 26 the mystery which [has been] hidden from ages and from generations, but has now been made manifest to his saints; 27 to whom God would make known what are the riches of the glory of this mystery among the nations, which is Christ in you the hope of glory: 28 whom we announce, admonishing every man, and teaching every man, in all wisdom, to the end that we may present every man perfect in Christ.

Matthew Henry's Commentary on Colossians 1:17-28

Commentary on Colossians 1:15-23

(Read Colossians 1:15-23)

Christ in his human nature, is the visible discovery of the invisible God, and he that hath seen Him hath seen the Father. Let us adore these mysteries in humble faith, and behold the glory of the Lord in Christ Jesus. He was born or begotten before all the creation, before any creature was made; which is the Scripture way of representing eternity, and by which the eternity of God is represented to us. All things being created by Him, were created for him; being made by his power, they were made according to his pleasure, and for his praise and glory. He not only created them all at first, but it is by the word of his power that they are upheld. Christ as Mediator is the Head of the body, the church; all grace and strength are from him; and the church is his body. All fulness dwells in him; a fulness of merit and righteousness, of strength and grace for us. God showed his justice in requiring full satisfaction. This mode of redeeming mankind by the death of Christ was most suitable. Here is presented to our view the method of being reconciled. And that, notwithstanding the hatred of sin on God's part, it pleased God to reconcile fallen man to himself. If convinced that we were enemies in our minds by wicked works, and that we are now reconciled to God by the sacrifice and death of Christ in our nature, we shall not attempt to explain away, nor yet think fully to comprehend these mysteries; but we shall see the glory of this plan of redemption, and rejoice in the hope set before us. If this be so, that God's love is so great to us, what shall we do now for God? Be frequent in prayer, and abound in holy duties; and live no more to yourselves, but to Christ. Christ died for us. But wherefore? That we should still live in sin? No; but that we should die to sin, and live henceforth not to ourselves, but to Him.

Commentary on Colossians 1:24-29

(Read Colossians 1:24-29)

Both the sufferings of the Head and of the members are called the sufferings of Christ, and make up, as it were, one body of sufferings. But He suffered for the redemption of the church; we suffer on other accounts; for we do but slightly taste that cup of afflictions of which Christ first drank deeply. A Christian may be said to fill up that which remains of the sufferings of Christ, when he takes up his cross, and after the pattern of Christ, bears patiently the afflictions God allots to him. Let us be thankful that God has made known to us mysteries hidden from ages and generations, and has showed the riches of his glory among us. As Christ is preached among us, let us seriously inquire, whether he dwells and reigns in us; for this alone can warrant our assured hope of his glory. We must be faithful to death, through all trials, that we may receive the crown of life, and obtain the end of our faith, the salvation of our souls.
