Why would a God create a man with the intent purpose of destroying himself? We have already established the duality of men. One with a carnal nature and one with a spiritual nature. Both serving the purposes of God. The spiritual Nature of course gives God a voice and the carnal nature is equipped to multiply itself. Now we all know the temporary nature of flesh and that therefore all flesh must die. But that is not the end it is only the beginning in other words spirt is eternal because God is spirit. God being one he had to find a way to multiply himself. The flesh is of course only a by product of this process. You could say that the carnal nature is a willing participant but instead it tried to establish it's own kingdom on earth. This believe it or not has greatly improved the productivity of the process. Without Satan, conquerors, mass murderers and weapons of all types fewer people would have died Even famine and pestilence have contributed to this process. There are now six billion humans on earth but there are already sixty million fruits in God's spiritual garden. No matter which way you decide to go we shall all be reconciled to God. There is however a small matter of rewards for those who gave God their voice.
