Hamartiology (Philosophical Theology of Sin, 2006) - God Created Humans As Mortals
God created humans as mortals. Mortality was known to Adam, or else reference to it in the command would have meant nothing to him....
...through Adam’s disobedience and choice of autonomy (physical well-being), mortality reached finality in Adam...."
(1) If man were created immortal, death could not be predicted of him in any condition. For “immortality” implies inability to die (physically). (2) If man were created immortal, the Tree of Life would be a meaningless addition to the Garden. Perhaps, a safer proposition might be “God created humans as neither mortals nor immortals” because of the condition of non-finality.
