Going from sister White quotes to your anti-nominian [lawlessness, which is sin 1 John 3:4 KJB] view is a bait and switch of the OP.
Jesus Christ is the perfect man, being the econd and last Adam, and he indeed obeyed the Law, and was sinless [ie transgressed not in a single precept], in thought, word or deed] as it is written:
John 15:10 KJB - If ye keep my commandments, ye shall abide in my love; even as I have kept my Father's commandments, and abide in his love.
Romans 9:30 KJB -What shall we say then? That the Gentiles, which followed not after righteousness, have attained to righteousness, even the righteousness which is of faith
Romans 9:31 KJB -But Israel, which followed after the law of righteousness, hath not attained to the law of righteousness.
Romans 9:32 KJB -Wherefore? Because they sought it not by faith, but as it were by the works of the law. For they stumbled at that stumblingstone;
Galatians 3:21 KJB - Is the law then against the promises of God? God forbid: for if there had been a law given which could have given life, verily righteousness should have been by the law.
The Law is never enough. Which is why the Law [Exodus 20:1-17 KJB] begins with God's mercy and salvation, read it:
Exodus 20:1 KJB - And God spake all these words, saying
Exodus 20:2 KJB - I am the LORD thy God, which have brought thee out of the land of Egypt, out of the house of bondage.
That is mercy/grace ... then followed by obedience in love, by strength given of God to accomplish what He says ...
Exodus 20:6 KJB - And shewing mercy unto thousands of them that love me, and keep my commandments.
John 14:15 KJB - If ye love me, keep my commandments.
In Exodus, it was the Lamb slain, then taken to the Law, and taken to the sanctuary, etc, etc.
