1 Corinthians 15:13-20

For if there is no such thing as a resurrection from the dead, then not even Christ has been raised. And if Christ has not been raised, all of our preaching has been for nothing and your faith is useless. Moreover, if the dead are not raised, that would mean that we are false witnesses who are misrepresenting God. And that would mean that we have preached a lie, stating that God raised him from the dead, if in reality he didn’t. If the dead aren’t raised up, that would mean that Christ has not been raised up either. And if Christ is not alive, you are still lost in your sins and your faith is a fantasy. It would also mean that those believers in Christ who have passed away have simply perished. If the only benefit of our hope in Christ is limited to this life on earth, we deserve to be pitied more than all others! But the truth is, Christ is risen from the dead, as the firstfruit of a great resurrection harvest of those who have died.
