You analogy does not make sense in this case. The simple answer is LOVE. Without Love free will does not exist. If there was no free will relationships would be basically forced. Would you really want a world with no free will?
See people focus so much on God saying not to eat from the tree of knowledge of good and evil. Me make our own choices due to free will. But what should be focused on is the fact that he actually has given us a way out of all this mess that WE put ourselves in. But people only want to focus on the tree.
To our human minds it would seem more efficient but how can we truly say that it is more efficient when we do not possess all knowledge. Since God has all knowledge and is good then he knows what is best for us. But we still have free will to choose what he has given us.
Okay but aside from the analogy why give us free will? And love or hunger, joy, sadness, pain, joy, etc. If we had no free will we would not know what these emotions/feeling mean. Sure we wouldn’t be aware of the good but we wouldn’t be aware of the bad either. Wouldn’t that be a more efficient way of running a society?
You know what I’m saying? The only reason we are aware of such feelings is because of free will. But what if instead we just fed our hunger by serving God? It’s like an out there theory. No hunger or thirst, sadness or happiness, need for shelter or money.
We’re just born and follow God’s word and that sustains us because we have no free will. I think that would be better
Good and bad have two authors. God=good. Satan=bad.
Once again we don't have all knowledge. What we think will be better will not be any better because we don't have all the information or understanding of what is the best way to run a society. Look at human history. We have tried numerous methods of running societies and it simply doesn't work.
As far as why God decided to give us emotions that's his decision.
Like I said he has given us a way out through Jesus. Don't worry about the flood just get in the boat and you'll be fine. One day all the evil will be gone. In fact it is promised.
