1 Corinthians 15:12-19

Now if Christ is preached as raised from the dead, how is it that some among you say that there is no resurrection of the dead? But if there is no resurrection of the dead, then not even Christ has been raised; 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]. We are even discovered to be false witnesses [misrepresenting] God, because we testified concerning Him that He raised Christ, whom He did not raise, if in fact the dead are not raised. For if the dead are not raised, then Christ has not been raised, either; and if Christ has not been raised, your faith is worthless and powerless [mere delusion]; you are still in your sins [and under the control and penalty of sin]. Then those also who have fallen asleep in Christ are lost. If we who are [abiding] in Christ have hoped only in this life [and this is all there is], then we are of all people most miserable and to be pitied.
