If the Spirit of the one who raised Jesus from the dead dwells in you, the one who raised Christ from the dead will give life to your mortal bodies also, through his Spirit that dwells in you.
Then we are also false witnesses to God, because we testified against God that he raised Christ, whom he did not raise if in fact the dead are not raised.
Otherwise, what will people accomplish by having themselves baptized for the dead? If the dead are not raised at all, then why are they having themselves baptized for them?
