1 Corinthians 15
15 Ref Yes, and we are seen to be false witnesses of God; because we gave witness of God that by his power Christ came again from the dead: which is not true if there is no coming back from the dead.
16 For if it is not possible for the dead to come to life again, then Christ has not come to life again:
17 Ref And if that is so, your faith is of no effect; you are still in your sins.
18 Ref And, in addition, the dead in Christ have gone to destruction.
19 Ref If in this life only we have hope in Christ, we are of all men most unhappy.
20 Ref But now Christ has truly come back from the dead, the first-fruits of those who are sleeping.
