As I see it, this is to do with the "law" to be written on human hearts rather than on tablets of stone.

Unfortunately, fundamentalist Christians in effect turn the letters of the New Testament into more "tablets of stone" and still insist that certain verses represent the "truth" and the "life", quoting them to exclude other human beings of other paths from God's grace. Therefore, blind leaders of the blind. The new Pharisees.
