1 Corinthians 15:12-14Amplified Bible (AMP)

¹² Now if Christ is preached as raised from the dead, how is it that ^[a]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].
