1 Corinthians 15:17-19

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.
