1 Corinthians 15:12-18

But tell me this—since we preach that Christ rose from the dead, why are some of you saying there will be no resurrection of the dead? For if there is no resurrection of the dead, then Christ has not been raised either. And if Christ has not been raised, then all our preaching is useless, and your faith is useless. And we apostles would all be lying about God—for we have said that God raised Christ from the grave. But that can’t be true if there is no resurrection of the dead. And if there is no resurrection of the dead, then Christ has not been raised. And if Christ has not been raised, then your faith is useless and you are still guilty of your sins. In that case, all who have died believing in Christ are lost!
