1 Corinthians 15:14 in the King James Version
And if Christ be not risen, then is our preaching vain, and your faith is also vain.
Context
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 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.
