God as I understand Him to be self-sustained, self-sufficient without need of anything. So what is God's purpose outside of recruiting His kingdom that in time will battle the dark forces that oppose the light of truth and good? However God as I understand Him to be is capable of defeating sin and darkness on His own merit because He is God. Why involve humans on the battle field of good and evil when God can restore the world to its former state at anytime? Perhaps God wants reassurance that sin does not enter into the world by choosing the inhabitants of the new world from those who are forgiven and redeemed from sin? Can you imagine life without pain and discourse? What will we do with ourselves without challenges and tension, how will we grow and learn? Will any of these things be important in another lifetime? Will overachievers live in harmony with slackers? Whatever, it.s not supposed matter anymore.
