God gives us the choice - either you're with Him or you can go your own way. Why? Because how genuine is love if there is no other choice?
And if you choose your own way, God always makes a way for His people to come back. That's why Jesus came - to fulfill the will of the Father to bring His people back to Himself. Jesus made a way. But some choose to stay in exile.
