1 Corinthians 15:14

12Now if Christ is preached, that he has been raised from the dead, how do some among you say that there is no resurrection of the dead?

13But if there is no resurrection of the dead, neither has Christ been raised.

14If Christ has not been raised, then our preaching is in vain and your faith also is in vain.

15Yes, we are also found false witnesses of God, because we testified about God that he raised up Christ, whom he didn’t raise up if it is true that the dead are not raised.

16For if the dead aren’t raised, neither has Christ been raised.
