24 Now I have joy in my pain because of you, and in my flesh I undergo whatever is still needed to make the sorrows of Christ complete, for the salvation of his body, the church; 25 Of which I became a servant by the purpose of God which was given to me for you, to give effect to the word of God, 26 The secret which has been kept from all times and generations, but has now been made clear to his saints, 27 To whom God was pleased to give knowledge of the wealth of the glory of this secret among the Gentiles, which is Christ in you, the hope of glory: 28 Whom we are preaching; guiding and teaching every man in all wisdom, so that every man may be complete in Christ; 29 And for this purpose I am working, using all my strength by the help of his power which is working in me strongly.

Matthew Henry's Commentary on Colossians 1:24-29

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.
