Colossians 1:21-29 English Standard Version (ESV)

²¹ And you, who once were alienated and hostile in mind, doing evil deeds, ²² he has now reconciled in his body of flesh by his death, in order to present you holy and blameless and above reproach before him, ²³ if indeed you continue in the faith, stable and steadfast, not shifting from the hope of the gospel that you heard, which has been proclaimed in all creation^[a] under heaven, and of which I, Paul, became a minister.

Paul's Ministry to the Church

²⁴ Now I rejoice in my sufferings for your sake, and in my flesh I am filling up what is lacking in Christ's afflictions for the sake of his body, that is, the church, ²⁵ of which I became a minister according to the stewardship from God that was given to me for you, to make the word of God fully known, ²⁶ the mystery hidden for ages and generations but now 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 Him we proclaim, warning everyone and teaching everyone with all wisdom, that we may present everyone mature in Christ. ²⁹ For this I toil, struggling with all his energy that he powerfully works within me.
