Some have thought that the law of God is only the moral law, while the law of Moses refers to the ceremonial law.
However the term “law of Moses” is not used in the first five books of the Bible. Those books include both moral and ceremonial law. The moral part of the law pointed out man’s duty to God; the ceremonial part pointed to the remedy for breaking the moral law. The prophets when using the term “law of Moses” often referred back to the first five books of the Bible. Notice the following:
Luke 2:22-24 And when the days of her purification according to the law of Moses were accomplished, they brought him to Jerusalem, to present him to the Lord; (As it is written in the law of the Lord, Every male that openeth the womb shall be called holy to the Lord;) And to offer a sacrifice according to that which is said in the law of the Lord, A pair of turtledoves, or two young pigeons.
You’ll notice that the term “law of Moses” is used in this passage, but you will also notice that it is interchanged with the term “law of the Lord”. The term “law of the Lord” is actually used to refer to the ceremonial law. Many today teach that the term “law of the Lord” is used only for the moral law, and the term “law of Moses” is used only for ceremonial law. But this idea is not found in the Bible, as demonstrated above.
In Leviticus 26 we read of many statutes including making idols (Lev 26:1) and the Sabbath (Lev 26:2). These commandments were written in stone by the finger of God. Throughout the chapter Jehovah explains what the consequences of violating these statutes would be, and finally says:
“These are the statutes and judgments and laws, which the LORD made between him and the children of Israel in mount Sinai by the hand of Moses.” (Lev 26:46)
God’s laws were given by Moses. The law of Moses includes the 10 commandments, and we would see this clearly if we read carefully.
Regarding the “law of God” which is sometimes referred to as the “law of Moses” we read the following:
“Remember ye the law of Moses my servant, which I commanded unto him in Horeb for all Israel, with the statutes and judgments. Behold, I will send you Elijah the prophet before the coming of the great and dreadful day of the LORD: and he shall turn the heart of the fathers to the children, and the heart of the children to their fathers, lest I come and smite the earth with a curse.” (Malachi 4:4-6)
The curse is written in the law, and the curse comes upon the one who “continueth not in all things which are written in the book of the law to do them.”(Gal 3:10) Diseases are a curse, and the curse has a cause. The cause is a violation of God’s law, which is sin. And “sin is transgression of the law” (1 John 3:4), and “the wages of sin is death”, and disease leads to death. All disease is the result of sin.
“And said, If thou wilt diligently hearken to the voice of the LORD thy God, and wilt do that which is right in his sight, and wilt give ear to his commandments, and keep all his statutes, I will put none of these diseases upon thee, which I have brought upon the Egyptians: for I am the LORD that healeth thee.” (Exod 15:26)
Will the curse still come upon those who refuse to accept that Christ has nailed the curse to the cross? (Gal 3:13) God’s way is the same today as it was then. (Gal 4:29, 2:16, 2:21)
