1 Corinthians 15:12-22

Now if Christ is proclaimed as raised from the dead, how can some of you say, “There is no resurrection of the dead”? But if there is no resurrection of the dead, then Christ has not been raised; and if Christ has not been raised, then our proclamation is without foundation, and so is your faith. In addition, we are found to be false witnesses about God, because we have testified about God that He raised up Christ — whom He did not raise up if in fact the dead are not raised. For if the dead are not raised, Christ has not been raised. And if Christ has not been raised, your faith is worthless; you are still in your sins. Therefore, those who have fallen asleep in Christ have also perished. If we have put our hope in Christ for this life only, we should be pitied more than anyone. But now Christ has been raised from the dead, the firstfruits of those who have fallen asleep. For since death came through a man, the resurrection of the dead also comes through a man. For as in Adam all die, so also in Christ all will be made alive.
