That's a thorny question for me. Can we survive if god allows us to have free will? In the Bible, we are told that god wishes for all to be saved, but we are also told that the path to salvation is long and narrow, and that few walk it. So god, who wishes for all to be saved, knows that very few will be saved. Isn't this a failure on his part?
The track record of free will is not encouraging. Apparently, every human being has sinned against god and at least a third of the angels, Satan included. Over a long enough time frame, the odds that everyone will cross god at some point are pretty even. Heaven will be a very lonely place.
