The ten commandments as worded in Exodus 20 and Deuteronomy 25 are not sufficient for spiritual Israel. As worded they are good for old covenant needs and allow for physical blessings. As worded they are very basic and don't require deep insight to keep them. Keeping them as written is keeping them in the letter. The arena of the Spirit is endless, to infinity. The letter of the law is limited. You don't want to miss a single word of this great sermon.
