13 But if there is no resurrection of the dead, neither hath Christ been raised: 14 and if Christ hath not been raised, then is our preaching vain, your faith also is vain. 15 Yea, we are found false witnesses of God; because we witnessed of God that he raised up Christ: whom he raised not up, if so be that the dead are not raised. 16 For if the dead are not raised, neither hath Christ been raised: 17 and if Christ hath not been raised, your faith is vain; ye are yet in your sins.
Matthew Henry's Commentary on 1 Corinthians 15:13-17
Commentary on 1 Corinthians 15:12-19
(Read 1 Corinthians 15:12-19)
Having shown that Christ was risen, the apostle answers those who said there would be no resurrection. There had been no justification, or salvation, if Christ had not risen. And must not faith in Christ be vain, and of no use, if he is still among the dead? The proof of the resurrection of the body is the resurrection of our Lord. Even those who died in the faith, had perished in their sins, if Christ had not risen. All who believe in Christ, have hope in him, as a Redeemer; hope for redemption and salvation by him; but if there is no resurrection, or future recompence, their hope in him can only be as to this life. And they must be in a worse condition than the rest of mankind, especially at the time, and under the circumstances, in which the apostles wrote; for then Christians were hated and persecuted by all men. But it is not so; they, of all men, enjoy solid comforts amidst all their difficulties and trials, even in the times of the sharpest persecution.
