12 Now if Christ is preached that he is raised from among [the] dead, how say some among you that there is not a resurrection of [those that are] dead? 13 But if there is not a resurrection of [those that are] dead, neither is Christ raised: 14 but if Christ is not raised, then, indeed, vain also [is] our preaching, and vain also your faith. 15 And we are found also false witnesses of God; for we have witnessed concerning God that he raised the Christ, whom he has not raised if indeed [those that are] dead are not raised. 16 For if [those that are] dead are not raised, neither is Christ raised; 17 but if Christ be not raised, your faith [is] vain; ye are yet in your sins.
Matthew Henry's Commentary on 1 Corinthians 15:12-17
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.
