1 Corinthians 15:13-17

But if there be no resurrection of the dead, then is Christ not risen:

And if Christ be not risen, then is our preaching vain, and your faith is also vain.

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.

For if the dead rise not, then is not Christ raised:

And if Christ be not raised, your faith is vain; ye are yet in your sins.
