Colossians 1:28 Meaning

26Even the mystery which hath been hid from ages and from generations, but now is made manifest to his saints:

27To whom God would make known what is the riches of the glory of this mystery among the Gentiles; which is Christ in you, the hope of glory:

28Whom we preach, warning every man, and teaching every man in all wisdom; that we may present every man perfect in Christ Jesus:

29Whereunto I also labour, striving according to his working, which worketh in me mightily.
