Colossians 1:27-29 NIV

[27] To them God has chosen to make known among the Gentiles the glorious riches of this mystery, which is Christ in you, the hope of glory. [28] He is the one we proclaim, admonishing and teaching everyone with all wisdom, so that we may present everyone fully mature in Christ. [29] To this end I strenuously contend with all the energy Christ so powerfully works in me.
