1 Corinthians 15:14 in the World English Bible
If Christ has not been raised, then our preaching is in vain and your faith also is in vain.
Context
13 But if there be no resurrection of the dead, then is Christ not risen:
14 And if Christ be not risen, then is our preaching vain, and your faith is also vain.
15 Yea, and we are found false witnesses of God; because we have testified of God that he raised up Christ: whom he raised not up, if so be that the dead rise not.
