In the Pentateuch, God tells men what to do. Our GOD is whom we follow in belief or behavior on earth in religious matters and whose counsel negates the law of Jesus (God).

Deuteronomy 12:32 ASV
(32)  What thing soever I command you, that shall ye observe to do: thou shalt not add thereto, nor diminish from it.

Matthew 28:20 ASV
(20)  teaching them to observe all things whatsoever I commanded you: and lo, I am with you always, even unto the end of the world.

Mark 7:7 ASV
(7) But in vain do they worship me, Teaching as their doctrines the precepts of men.
