Paul labours according to the ministry the Lord Jesus Christ gave him. He describes himself as being a minister of the dispensation of God, the mystery...

When Paul speaks of the dispensation of God, he speaks as the chosen apostle to the Gentiles. Paul preaches Jesus Christ according to the revelation of the mystery, as we ought to as well.

Paul makes it clear to the Colossians that what he is communicating is the revelation of the mystery of Christ which was given to him by the resurrected, glorified, Lord Jesus Christ. The news of "Christ in you, the hope of glory" is an amazing truth! That Gentiles can be saved without Israel, without the law, and without the covenants has been revealed to us through Paul, the apostle of the Gentiles.
