1 Corinthians 15:16

14 And if Christ has not been raised, our preaching is worthless, and so is your faith.

15 In that case, we are also exposed as 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.

For if the dead are not raised, then not even Christ has been raised.

17 And if Christ has not been raised, your faith is futile; you are still in your sins.

18 Then those also who have fallen asleep in Christ have perished.

Do read the surrounding verses too, because the context often says more than a single verse.
