Had Adam and Eve retained their original state, they never would have died. But Eve and then Adam yielded to the serpent’s temptation, and death came into the world. Before that moment, they were in a beautiful, pristine state. They existed on a level far above the present condition of the human race. It is difficult to imagine what man was like then by viewing him as he is now. It would require something like trying to reconstruct the original version of an aircraft from its wreckage. If we knew nothing of flying, we would hardly suspect that it had once soared above the earth. The material would be the same; the capability of flight, however, would be lost.
