How long after Adam was the Law given at Mount Sinai?
The Law was given at Mount Sinai 2,500 years after Adam was created. It was added because of transgressions, sin, and came after the human race had begun, with no organized system of worship or written commandments existing before that time.
Les explains that the Law was brought in 2,500 years after the human race had begun because of transgressions, sin. He notes that up until the Law was given at Mount Sinai—2,500 years after Adam was created—there was no system of worship, no organized religion as we call it, and no written 'Thou shalt' and 'Thou shalt not.' To illustrate how sin ran rampant before the Law, he points to Genesis 6:5, where God saw that the wickedness of man was great in the earth and that every imagination of the thoughts of his heart was only evil continually.
