The deal, as I understand it, is that God will forgive you as many times as you ask for it, but it's up to you to maintain a relationship with God. In other words, you have to try to be good. You've got to meet Him half-way. Its easy, the rules are simple. There are only ten.
"There are only ten."
Well, 10 rules as you present them doesn't make sense really. If it did, the O.T. would have never become 'old'.
