Or else what will those do who are baptized for the dead?

AT: "Otherwise it would be useless for Christians to receive baptism for the dead" (See: rc://en/ta/man/translate/figs-rquestion)

be baptized for the dead

"receive baptism on behalf of dead people"

And why are we in danger every hour?

If Jesus did not rise from the dead, then there is no justification for Paul & other christians to be in danger regarding their beliefs and teachings.
