1 Corinthians 15:13-17 (New International Version)

¹³If there is no resurrection of the dead, then not even Christ has been raised. ¹⁴And if Christ has not been raised, our preaching is useless and so is your faith. ¹⁵More than that, we are then found to be false witnesses about God, for we have testified about God that he raised Christ from the dead. But he did not raise him if in fact the dead are not raised. ¹⁶For if the dead are not raised, then Christ has not been raised either. ¹⁷And if Christ has not been raised, your faith is futile; you are still in your sins.
