In another thread a comment concerning the "tree of life" was mentioned. I have never thought about it before so let me ask: If mankind was immortal before the fall, why was there a tree of life in the garden of eden? Along the same lines, something else I have often wondered about. Since Jesus Christ was sinless and did not have a sin nature, why did he grow old. Old age leads to death, but since Christ was not a sinner in any sense of the word, shouldn't he have lived for ever, if not for the crucification?
