There are some who say that God’s law didn’t come into being until it was given at Mt. Sinai. The following is why I disagree.

• God’s law is His character. So the law, by its nature, is eternal.
• God’s word is law. That’s why sin came about when Adam broke “Do not eat from that one tree.”
• Cain was credited with sin for killing his brother (1 John 3: 12). Sin can’t be charged if there’s no law.
• Abraham, before there was a Jewish nation, was honored for keeping God’s commandments, statutes, and laws (Genesis 26: 5).
• Before Sinai, God scolded His people for disobeying His commandments and laws (Exodus 16: 28, 29).

Those who think the law was instituted at Mt. Sinai base their reasoning on Romans 5: 13. It reads…

“For until the law sin was in the world, but sin is not imputed when there is no law.”

Specifically, it’s the phrase “until the law” that makes them think it didn’t exist between the Garden of Eden and Mt. Sinai.

But, as has been shown, the law was in effect during that period. It was known throughout the world by word of mouth that was passed down through the generations.

“Until the law” clearly means that the law altogether did not exist in written form until it was given at Mt. Sinai.
