Yet, the standard religious doctrine also teaches that if the lowly human being is very good, behaves himself and "believes unto the Lord," he will earn eternal life. It is likewise widely believed that certain of the biblical "prophets," such as Elijah and Moses, were able to attain to this status of immortality, as their appearance from the otherworld next to the "son of Man" was purported in the New Testament. (Mk 9:4) Thus, it is obvious that even mortals can attain to immortality, according to this belief system.
