Maybe God's commandments are not such a bad standard after all. Only those who obey out of love are acceptable to God, and these will receive eternal life in His kingdom. When God gave His creatures free will, He intended for them to have it for eternity. But only those who have developed a heartfelt respect for God's law can be trusted not to plunge the universe into misery again. In God's time, only these will be allowed the privilege of living there.
People do it.
So could you. Be sure of one thing. Disobedience to God's law is not the prelude to murder. This is not legalism, but educated loyalty, lived out in a willing heart. He reaffirms this twice more in the same chapter.
