Colossians 1:26-28

The mystery of which was hidden for ages and generations [from angels and men], but is now revealed to His holy people (the saints), To whom God was pleased to make known how great for the Gentiles are the riches of the glory of this mystery, which is Christ within and among you, the Hope of [realizing the] glory. Him we preach and proclaim, warning and admonishing everyone and instructing everyone in all wisdom (comprehensive insight into the ways and purposes of God), that we may present every person mature (full-grown, fully initiated, complete, and perfect) in Christ (the Anointed One).
