1 Corinthians 15:12-14

12 Now if Christ is preached as raised from the dead, how is it that[3] some among you say that there is no resurrection of the dead?

13 But if there is no resurrection of the dead, then not even Christ has been raised;

14 and if Christ has not been raised, then our preaching is vain [useless, amounting to nothing], and your faith is also vain [imaginary, unfounded, devoid of value and benefit—not based on truth].
