1 Corinthians 15:12-16

12But if it is preached that Christ has been raised from the dead, how can some of you say that there is no resurrection of the dead?

13If there is no resurrection of the dead, then not even Christ has been raised.

14And if Christ has not been raised, our preaching is useless and so is your faith.

15More than that, we are then found to be false witnesses about God, for we have testified about God that he raised Christ from the dead. But he did not raise him if in fact the dead are not raised.

16For if the dead are not raised, then Christ has not been raised either.
