The greatest mystery ever revealed was not a man-made plot for treasures or trinkets of this earth, but the glorious and eternal plan of God to send His Son Jesus Christ to save both Jews and Gentiles, as Paul said, "Christ in you, the hope of glory." Paul's gospel was the gospel of grace which he received and which he proclaimed. Have you received this grace? it only comes through repentance and receiving Christ as Savior and Lord.
