Abn Iblis ابن إبليس
If God ceased to exist, no one would have anything to live for.
I don't know why people have this weird dichotomy that God's sole purpose is to keep us from doing bad things. The reality is that God is what makes everything good, whether we like it or not. Without God, there would literally be nothing worth living for in the world.
Imagine the despair of the Holocaust, except remove all hope, and you've got a glimpse of what the world would be like without God. Hope is life. Despair is death.
First of all tomspug: if God ceased to exist that would mean God existed. But I know what you mean. Even so, the existence of God does not keep 'us' from doing anything. God is but the conscience of the Universe, not a being that wishes or wants or dictates things.
Hope and despair are Earthly principals and not something that concerns a Divine being.
