'Dead Rise' in the Bible

Yea, and we are found false witnesses of God, because we testified from God, that he raised up Christ, whom he did not raise, if the dead rise not.

For if the dead rise not, neither is Christ raised:

Else what shall they do, who are baptized for the dead? If the dead rise not at all, why are they then baptized for them?

I have fought with wild beasts at Ephesus, what advantageth it me, if the dead rise not? Let us eat and drink; for tomorrow we die.
