What the Bible says about Rules, Living by God's
(From Forerunner Commentary)
We are being prepared for living in a community in which no one hurts or destroys because everybody lives by the same rules—not their own rules, but "the knowledge of the LORD," God's rules! What if we are not practiced at living by God's rules or never cared to pay attention to them? What if we thought one or two of them were rather silly, so we did not need to live according to them? We would not "fit" in His holy mountain any more than a person would fit in a game in which everyone was playing by the rules except him. He would ruin the game. That is the point.
