1 Corinthians 15:16 Meaning

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

15Yea, 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.

16For if the dead rise not, then is not Christ raised:

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

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