What is the Law of God?

God spake all these words, saying,

What rules are to be observed for the right understanding of the ten commandments? Exodus 20

For the right understanding of the ten commandments, these rules are to be observed:

1. That the law is perfect, and binds everyone to full conformity in the whole man unto the righteousness thereof, and unto entire obedience forever; so as to require the utmost perfection of every duty, and to forbid the least degree of every sin.

 The law of the LORD is perfect, converting the soul: the testimony of the LORD is sure, making wise the simple. (Psalm 19:7)

 Ye have heard that it was said by them of old time, Thou shalt not kill; and whosoever shall kill shall be in danger of the judgment:  But I say unto you, That whosoever is angry with his brother without a cause shall be in danger of the judgment: and whosoever shall say to his brother, Raca, shall be in danger of the council: but whosoever shall say, Thou fool, shall be in danger of hell fire. (Matthew 5:21-22)

For whosoever shall keep the whole law, and yet offend in one point, he is guilty of all. (James 2:10)

2. That it is spiritual, and so reaches the understanding, will, affections, and all other powers of the soul; as well as words, works, and gestures.

 For we know that the law is spiritual: but I am carnal, sold under sin. (Romans 7:14)

And thou shalt love the LORD thy God with all thine heart, and with all thy soul, and with all thy might. (Deuteronomy 6:5)

 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. This is the first and great commandment. And the second is like unto it, Thou shalt love thy neighbour as thyself. (Matthew 22:37-39)

3. That one and the same thing, in divers respects, is required or forbidden in several commandments.

Mortify therefore your members which are upon the earth; fornication, uncleanness, inordinate affection, evil concupiscence, and covetousness, which is idolatry: (Colossians 3:5)

Saying, When will the new moon be gone, that we may sell corn? and the sabbath, that we may set forth wheat, making the ephah small, and the shekel great, and falsifying the balances by deceit? (Amos 8:5)

So are the ways of every one that is greedy of gain; which taketh away the life of the owners thereof. (Proverbs 1:19)

For the love of money is the root of all evil: which while some coveted after, they have erred from the faith, and pierced themselves through with many sorrows. (1 Timothy 6:10)

4. That as, where a duty is commanded, the contrary sin is forbidden; and, where a sin is forbidden, the contrary duty is commanded: so, where a promise is annexed, the contrary threatening is included; and, where a threatening is annexed, the contrary promise is included.

If thou turn away thy foot from the sabbath, from doing thy pleasure on my holy day; and call the sabbath a delight, the holy of the LORD, honourable; and shalt honour him, not doing thine own ways, nor finding thine own pleasure, nor speaking thine own words: (Isaiah 58:13)

Thou shalt fear the LORD thy God, and serve him, and shalt swear by his name. (Deuteronomy 6:13)

And saith unto him, All these things will I give thee, if thou wilt fall down and worship me. Then saith Jesus unto him, Get thee hence, Satan: for it is written, Thou shalt worship the Lord thy God, and him only shalt thou serve. (Matthew 4:9-10)

For God commanded, saying, Honour thy father and mother: and, He that curseth father or mother, let him die the death. But ye say, Whosoever shall say to his father or his mother, It is a gift, by whatsoever thou mightest be profited by me; And honour not his father or his mother, he shall be free. Thus have ye made the commandment of God of none effect by your tradition. (Matthew 15:4-6)

Let him that stole steal no more: but rather let him labour, working with his hands the thing which is good, that he may have to give to him that needeth. (Ephesians 4:28)

Honour thy father and thy mother: that thy days may be long upon the land which the LORD thy God giveth thee. (Exodus 20:12)

The eye that mocketh at his father, and despiseth to obey his mother, the ravens of the valley shall pick it out, and the young eagles shall eat it. (Proverbs 30:17)

At what instant I shall speak concerning a nation, and concerning a kingdom, to pluck up, and to pull down, and to destroy it; If that nation, against whom I have pronounced, turn from their evil, I will repent of the evil that I thought to do unto them. (Jeremiah 18:7-8)

Thou shalt not take the name of the LORD thy God in vain; for the LORD will not hold him guiltless that taketh his name in vain. (Exodus 20:7)

In whose eyes a vile person is contemned; but he honoureth them that fear the LORD. He that sweareth to his own hurt, and changeth not. He that putteth not out his money to usury, nor taketh reward against the innocent. He that doeth these things shall never be moved. (Psalm 15:4-5)

He that hath clean hands, and a pure heart; who hath not lifted up his soul unto vanity, nor sworn deceitfully. He shall receive the blessing from the LORD, and righteousness from the God of his salvation. (Psalm 24:4-5)

5.That what God forbids, is at no time to be done; what he commands, is always our duty; and yet every particular duty is not to be done at all times.

And not rather, (as we be slanderously reported, and as some affirm that we say,) Let us do evil, that good may come? whose damnation is just. (Romans 3:8)

Choosing rather to suffer affliction with the people of God, than to enjoy the pleasures of sin for a season; (Hebrews 11:25)

And what nation is there so great, that hath statutes and judgments so righteous as all this law, which I set before you this day?  Only take heed to thyself, and keep thy soul diligently, lest thou forget the things which thine eyes have seen, and lest they depart from thy heart all the days of thy life: but teach them thy sons, and thy sons' sons; (Deuteronomy 4:8‑9)

But if ye had known what this meaneth, I will have mercy, and not sacrifice, ye would not have condemned the guiltless. (Matthew 12:7)

6. That under one sin or duty, all of the same kind are forbidden or commanded; together with all the causes, means, occasions, and appearances thereof, and provocations thereunto.

Abstain from all appearance of evil. (1 Thessalonians 5:22)

And others save with fear, pulling them out of the fire; hating even the garment spotted by the flesh. (Jude 23)

Fathers, provoke not your children to anger, lest they be discouraged. (Colossians 3:21)

7. That what is forbidden or commanded to ourselves, we are bound, according to our places, to endeavor that it may be avoided or performed by others, according to the duty of their places.
