1 Corinthians 15:15 WEB

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

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

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

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

¹⁷  If Christ has not been raised, your faith is vain; you are still in your sins.
