Colossians 1:26-27

Amplified Bible

²⁶ that is, ^[a]the mystery which was hidden [from angels and mankind] for ages and generations, but has now been revealed to His saints (God’s people). ²⁷ God [in His eternal plan] chose to make known to them how great for the Gentiles are the riches of the glory of this mystery, which is Christ in and among you, the hope and guarantee of [realizing the] glory.
