Paul gives a defense of the doctrine of resurrection by showing that a denial of such is a denial of a resurrected Christ, entailing its dangers, contradictions and absurdities, but in return, affirming it brings hope and joy to the believer.
I. The Denial of the Resurrection is a denial of Christ (v. 12-13)
II. The Consequences of this Denial (v. 14-18)
III. The Summation of the Christian life without Resurrection (v. 19)
