Should the wages of sin be death and that death is a spiritual death, then Jesus' death was of nothing.
1Co 15:12 Now, if, Christ is proclaimed, that, from among the dead, he hath been raised, how say some, among you—resurrection of the dead, there is none?
1Co 15:13 But, if, resurrection of the dead, there is none, not even Christ, hath been raised;
1Co 15:14 And, if Christ, hath not been raised, void, after all, is our proclamation, void also, our faith,—
1Co 15:15 And we are found, even false-witnesses of God, because we have witnessed respecting God, that he raised the Christ,—whom he did not raise, if, indeed, after all, the dead are not raised!
1Co 15:16 For, if the dead are not raised, not even Christ, hath been raised;
1Co 15:17 And, if Christ hath not been raised, to no purpose, is your faith, yet, are ye in your sins!
1Co 15:18 Hence also, they who are fallen asleep in Christ, are lost:
1Co 15:19 If, in this life, in Christ, we have hoped—and that is all, we are, of all men, most to be pitied.
