1:26 that is, the mystery that has been kept hidden from ages and generations, but has now been revealed to his saints.
1:27 God wanted to make known to them the glorious riches of this mystery among the Gentiles, which is Christ in you, the hope of glory.
1:28 We proclaim him by instructing and teaching all people with all wisdom so that we may present every person mature in Christ.
