1 Corinthians 15:14

Whether then it is I or they, so we preach, and so you believed.

Now 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?

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

Yes, 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.

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

If Christ has not been raised, your faith is vain; you are still in your sins.
