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.
19. If our hopes in Christ were limited to this life only, we should be, of all men, most to be pitied; namely, because, while others live unmolested, we are exposed to every trial and persecution, and, after all, are doomed to bitter disappointment in our most cherished hope; for all our hope of salvation, even of the soul (not merely of the body), hangs on the resurrection of Christ, without which His death would be of no avail to us (Eph 1:19, 20; 1Pe 1:3). The heathen are "without hope" (Eph 2:12; 1Th 4:13). We should be even worse, for we should be also without present enjoyment (1Co 4:9).
