Colossians 1:24-29 (NRSV)
24 I am now rejoicing in my sufferings for your sake, and in my flesh I am completing what is lacking in Christ’s afflictions for the sake of his body, that is, the church. 25 I became its servant according to God’s commission that was given to me for you, to make the word of God fully known, 26 the mystery that has been hidden throughout the ages and generations but has now been revealed to his saints. 27 To them God chose to make known how great among the Gentiles are the riches of the glory of this mystery, which is Christ in you, the hope of glory. 28 It is he whom we proclaim, warning everyone and teaching everyone in all wisdom, so that we may present everyone mature in Christ. 29 For this I toil and struggle with all the energy that he powerfully inspires within me.
