1 Corinthians 15:16

14 And if Christ be not risen, then is our preaching vain, and your faith is also vain.

15 Yea, and we are found false witnesses of God; because we have testified of God that he raised up Christ: whom he raised not up, if so be that the dead rise not.

For if the dead rise not, then is not Christ raised:

17 And if Christ be not raised, your faith is vain; ye are yet in your sins.

18 Then they also which are fallen asleep in Christ are perished.

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