And God doesn't demand good behavior through force? I don't see the distinction.
The distinction is that with God you have a choice. God doesn't force you to behave regardless of what think.
God is a libertarian. You decide how to live your life, and you reap the rewards of you are good, or the consequences if you are evil. Its still your choice, and your responsibility.
Gov't uses force. Mis-behave, you go to jail. Disagree with the majority? Too bad, you still have to go along with them or go to jail. Gov't is inherently authoritarian, the opposite of God.
