Steve7150, you wrote:For some reason beyond just punishment, i think God decided mankind as a whole needs to experience evil for a greater good.
Apparently that concept was around even in apostolic times. Paul wrote:
Romans 3:8 And why not do evil that good may come?—as some people slanderously charge us with saying. Their condemnation is just.
That concept is exactly what turns millions of people against God. If God has a greater good which comes out of evil, whether moral evil, or "natural" evil, why does He not tell us what this greater good is, so that we can learn our lesson?
But if Adam and Eve had never succumbed to Satan's tempation and had never sinned, what need would there be for "spiritual muscles"?You also wrote:We do know overcoming physical resistence builds physical muscles so perhaps the same principal applies spiritually.
