"Transgression of physical law is transgression of the moral law; for God is as truly the author of physical laws as He is the author of the moral law. His law is written with His own finger upon every nerve, every muscle, every faculty, which has been entrusted to man. And every misuse of any part of our organism is a violation of that law. COL 347.1"
"Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another;)"
Both passages connect law and the human body/heart. Romans 2:15 speaks of the law written on the heart, while EGW speaks of physical law being written on the body. There is a thematic parallel in the idea of God's law being intrinsically linked to human existence.
