Always bearing about in the body the dying of the Lord Jesus...
The gospel is the death, burial, and resurrection of Christ. 1 Cor. 15:1-4. We must not only believe in it but we must enter into it and continue to participate in it. Col. 1:21-23; Rom. 11:22; 1 Cor. 15:2. We do this by faith in Him and His finished work on the cross and not by self-effort. Gal. 3:1-5.
