'Mortal' in the Bible

For the Messiah also suffered for sins once for all, an innocent person for the guilty, so that he could bring you to God. He was put to death in a mortal body but was brought to life by the Spirit,

Therefore, since the Messiah suffered in a mortal body, you, too, must arm yourselves with the same determination, because the person who has suffered in a mortal body has stopped sinning,

so that he can live the rest of his mortal life guided, not by human desires, but by the will of God.

Indeed, this is why the gospel was proclaimed even to those who have died, so that they could be judged in their mortal flesh like all humans and live in the spiritual realm like God.
