Deuteronomy 5:22
22These words the LORD spake unto all your assembly in the mount out of the midst of the fire, of the cloud, and of the thick darkness, with a great voice: and he added no more. And he wrote them in two tables of stone, and delivered them unto me.
We are commanded to hear the voice of the LORD God. Outside of that, He added no more. The ten commandments of God are the ONLY commandments that are Spirit. These commandments are summed up in love. Indeed, His burden is light.
