Colossians 1:26

26. Mystery The word used of facts and truths not fully revealed, occurs four times in this epistle, and in that to the Ephesians six times, and always, with a single exception in the latter, with a reference more or less direct to Christ. Here it is the doctrine of salvation through Christ, or, more simply, Christ himself. He had not been revealed to former ages of the world, for they were not prepared to receive a Saviour; and even the angels had not fully comprehended the great plan. Now he is revealed to the apostles, (Ephesians 3:5,) preached by them, believed in, and thus is made manifest to his saints. Believers know Christ.
