Colossians 1:25-29

²⁵of 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,²⁶the mystery hidden for ages and generations but now revealed to his saints.  ²⁷To 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.  ²⁸Him we proclaim, warning everyone and teaching everyone with all wisdom, that we may present everyone mature in Christ.  ²⁹For this I toil, struggling with all his energy that he powerfully works within me.
