"And the dragon was wroth with the woman, and went to make war with the remnant of her seed, which keep the commandments of God, and have the testimony of Jesus Christ." Rev. 12:17
"Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus." - Rev. 14:12
We were given ten instructions on how to live by the Father in the OT. We are bound by these until Judgement Day. Some state differently, arguing that the above passages refer to general commands by God, not the 10 commandments, referencing other passages using the word commandment. Yet the Greek word for commandments (entolē) in the above passages differs from the word for "commandment" used in the passages which merely means command, not commandment. If you unsure about the meaning of a word listed in the KJV, merely check the Strong Concordance to get the original meaning of it in Hebrew (OT) or Greek (NT).
"By this we know that we love the children of God, when we love God, and keep his commandments. For this is the love of God, that we keep his commandments: and his commandments are not grievous." - John 5:2-4
Later, when Yeshua arrived, He gave us two new instructions. These did not replace the original commandments, but summarized them; all ten commandments can be summed up in two.
"Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil."
- Matt. 5:17
This does not means that we can now disregard them as some teach. The Greek word written for fulfill means to perfect. Yeshua perfected the ten commandments which we are still bound by.
And while it is our faith which allows us entrance into the kingdom of heaven, it is our obedience to the Law which determines our rank in it...
"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." - Matt. 5:19
"Blessed are they that do his commandments, they may have right to the tree of life, and may enter in through the gates into the city."
- Rev. 22-14
1. Thou shalt have no other gods before me.
2. 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.
3. 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.
4. Remember the sabbath day, to keep it holy. Six days shalt thou labour, and do all thy work. But the seventh day [Saturday] is the sabbath of the Lord thy God: in it thou shalt not do any work.
5. Honour thy father and thy mother.
6. Thou shalt not kill.
7. Thou shalt not commit adultery.
8. Thou shalt not steal.
9. Thou shalt not bear false witness against thy neighbour.
10. Thou shalt not covet [desire]... anything that is thy neighbour's.
1. 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.
2. Thou shalt love thy neighbour as thyself.
"On these two commandments hang all the law and the prophets." - Matt. 22:40
"If ye love me, keep my commandments." - John 14:15
