Once one is convinced of the idea of eternal life or death, the person may do almost anything to achieve the reward or avoid punishment. He may fly an airplane into a building or become a missionary to another county. She may become a celibate nun or vow to raise a quiver full of children and homeschool them according to her religion.

The root of this action is the hope for a reward and avoidance of punishment.
