1 Corinthians 15:29-35 ESV
Otherwise, what do people mean by being baptized on behalf of the dead? If the dead are not raised at all, why are people baptized on their behalf? Why are we in danger every hour? I protest, brothers, by my pride in you, which I have in Christ Jesus our Lord, I die every day! What do I gain if, humanly speaking, I fought with beasts at Ephesus? If the dead are not raised, “Let us eat and drink, for tomorrow we die.” Do not be deceived: “Bad company ruins good morals.” Wake up from your drunken stupor, as is right, and do not go on sinning. For some have no knowledge of God. I say this to your shame.
But someone will ask, “How are the dead raised? With what kind of body do they come?”
