The moral law is summarily comprehended in the ten commandments.115
Matthew 19:17-19. And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments. He saith unto him, Which? Jesus said, Thou shalt do no murder, Thou shalt not commit adultery, Thou shalt not steal, Thou shalt not bear false witness, Honour thy father and thy mother: and, Thou shalt love thy neighbour as thyself.
The sum of the ten commandments is, to love the Lord our God with all our heart, with all our soul, with all our strength, and with all our mind; and our neighbor as ourselves.116
The preface to the ten commandments is in these words, I am the Lord thy God, which have brought thee out of the land of Egypt, out of the house of bondage.117
Deuteronomy 5:6. I am the LORD thy God, which brought thee out of the land of Egypt, from the house of bondage.
The preface to the ten commandments teacheth us, that because God is the Lord, and our God, and Redeemer, therefore we are bound to keep all his commandments.118
1 Peter 1:14-19. As obedient children, not fashioning yourselves according to the former lusts in your ignorance: But as he which hath called you is holy, so be ye holy in all manner of conversation; Because it is written, Be ye holy; for I am holy. And if ye call on the Father, who without respect of persons judgeth according to every man’s work, pass the time of your sojourning here in fear: Forasmuch as ye know that ye were not redeemed with corruptible things, as silver and gold, from your vain conversation received by tradition from your fathers; But with the precious blood of Christ, as of a lamb without blemish and without spot.
The first commandment is, Thou shalt have no other gods before me.119
Deuteronomy 5:7. Thou shalt have none other gods before me.
The first commandment requireth us to know and acknowledge God to be the only true God, and our God; and to worship and glorify him accordingly.120
Isaiah 45:20-25. Assemble yourselves and come; draw near together, ye that are escaped of the nations: they have no knowledge that set up the wood of their graven image, and pray unto a god that cannot save. Tell ye, and bring them near; yea, let them take counsel together: who hath declared this from ancient time? who hath told it from that time? have not I the LORD? and there is no God else beside me; a just God and a Saviour; there is none beside me. Look unto me, and be ye saved, all the ends of the earth: for I am God, and there is none else. I have sworn by myself, the word is gone out of my mouth in righteousness, and shall not return, That unto me every knee shall bow, every tongue shall swear. Surely, shall one say, in the LORD have I righteousness and strength: even to him shall men come; and all that are incensed against him shall be ashamed. In the LORD shall all the seed of Israel be justified, and shall glory.
Matthew 4:10. 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.
The first commandment forbiddeth the denying,121 or not worshiping and glorifying, the true God as God,122 and our God;123 and the giving of that worship and glory to any other, which is due to him alone.124
Romans 1:25. Who changed the truth of God into a lie, and worshipped and served the creature more than the Creator, who is blessed for ever. Amen.
These words before me in the first commandment teach us, that God, who seeth all things, taketh notice of, and is much displeased with, the sin of having any other God.125
Psalm 44:20-21. If we have forgotten the name of our God, or stretched out our hands to a strange god; Shall not God search this out? for he knoweth the secrets of the heart.
Ezekiel 8:12. Then said he unto me, Son of man, hast thou seen what the ancients of the house of Israel do in the dark, every man in the chambers of his imagery? for they say, The LORD seeth us not; the LORD hath forsaken the earth.
Thou shalt not make unto thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the water under the earth: Thou shalt not bow down thyself to them, nor serve them: for I the LORD thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me; And shewing mercy unto thousands of them that love me, and keep my commandments.126
Deuteronomy 5:8-10. Thou shalt not make thee any graven image, or any likeness of any thing that is in heaven above, or that is in the earth beneath, or that is in the waters beneath the earth: Thou shalt not bow down thyself unto them, nor serve them: for I the LORD thy God am a jealous God, visiting the iniquity of the fathers upon the children unto the third and fourth generation of them that hate me, And showing mercy unto thousands of them that love me and keep my commandments.
The second commandment requireth the receiving, observing, and keeping pure and entire, all such religious worship and ordinances as God hath appointed in his Word.127
Matthew 28:20. Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the world. Amen.
