Up until the Fall, the Creator's Word was the test and standard for truth. All ideas were compared to what the Creator said. Any idea that didn't agree would therefore be wrong because the Creator would not lie. At the Fall, man was tempted to move away from the Creator's standard of truth, and to substitute his own. As a result, death came into the universe.
Death is abnormal.
Man was not created to die. We have a right to cry at a funeral. Death entered the world when man sinned. That phrase should stand out like a red neon sign. All of the rest of Scripture, and even in our culture today, children take the father's name.
