What has already been written is Death. To eat from the tree of the Knowledge of good and evil is Death. The Law of Moses is a covenant with Death. The letter of the written word is Death.
Genesis 2:17
But of the tree of the knowledge of good and evil, thou shalt not eat of it: for in the day that thou eatest thereof thou shalt surely die.
Isaiah 28:15
Because ye have said, We have made a covenant with death,
and with hell are we at agreement;
when the overflowing scourge shall pass through, it shall not come unto us:
for we have made lies our refuge,
and under falsehood have we hid ourselves:
Romans 7:9
For I was alive without the law once: but when the commandment came, sin revived, and I died.
2 Corinthians 3:6
Who also hath made us able ministers of the new testament; not of the letter, but of the spirit: for the letter killeth, but the spirit giveth life.
2 Corinthians 3:7
But if the ministration of death, written and engraven in stones, was glorious, so that the children of Israel could not stedfastly behold the face of Moses for the glory of his countenance; which glory was to be done away:
The written law does bring death, but the Spirit gives life. We are ministers of a new testament, not of letter, but by Spirit, 2 Corinthians Chapter 3.
There are laws (commandments) of God that were especially written just for the Hebrews pertaining to the rituals of the Temple, sacrifices, festivals, Torah, Kohanim and Levites, the King and the Nazarite. These have already been fulfilled in Christ, but yet there are the existing commandments with the greatest one being love that we follow in as in the existing moral laws (commandments) for all of us to still follow as in prayers and blessings, love and brotherhood. The poor and unfortunate, Marriage, divorce and family. Forbidden sexual relations, business practices, employees and servants. Vows, oaths, swearing, Court and Judicial procedures. Injuries and damages, property and property rights, criminal laws. Prophecy, idolatry and all its practices as the moral laws (commandments) keep us in line with the will of God.
The law is not Satan's authority, but God's authority that Satan rebels against being the enmity against God. The greatest commandment is love that if we walk in love that will help us be obedient to God's moral laws.
Mat 5:17 Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil.
Mat 5:18 For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.
Mat 5:19 Whosoever therefore shall break one of these least commandments, and shall teach men so, he shall be called the least in the kingdom of heaven: but whosoever shall do and teach them, the same shall be called great in the kingdom of heaven.
Mat 22:36 Master, which is the great commandment in the law?
Mat 22:37 Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.
Mat 22:38 This is the first and great commandment.
Mat 22:39 And the second is like unto it, Thou shalt love thy neighbour as thyself.
Mat 22:40 On these two commandments hang all the law and the prophets.
