1 Corinthians 15:12-19(NKJV)
12Now if Christ is preached that He has been raised from the dead, how do some among you say that there is no resurrection of the dead?
13But if there is no resurrection of the dead, then Christ is not risen.
14And if Christ is not risen, then our preaching is empty and your faith is also empty.
15Yes, and we are found false witnesses of God, because we have testified of God that He raised up Christ, whom He did not raise upif in fact the dead do not rise.
16For if the dead do not rise, then Christ is not risen.
17And if Christ is not risen, your faith is futile; you are still in your sins!
18Then also those who have fallen asleep in Christ have perished.
19If in this life only we have hope in Christ, we are of all men the most pitiable.
there has to be a resurrection of the dead or else they will never live again!
