"For if the message spoken by angels was binding, and every violation and disobedience received its just punishment, how shall we escape if we ignore such a great salvation? This salvation, which was first announced by the Lord, was confirmed to us by those who heard him" (Hebrews 2:2-3)
Part 2 of 2
"Anyone who rejected the law of Moses died without mercy on the testimony of two or three witnesses. How much more severely do you think a man deserves to be punished who has trampled the Son of God under foot, who has treated as an unholy thing the blood of the covenant that sanctified him, and who has insulted the Spirit of grace?" (Hebrews 10:28-29)
When the law was given, it was put into effect and ratified by the angels (Acts 7:38; Acts 7:53; Galatians 3:19; Hebrews 2:1). It proved authentic and every act of disobedience against it was judged and received swift punishment. In fact one of the first offenses after the law was given was a man who was stoned to death because he was picking up sticks on the Sabbath Day, which was forbidden (Numbers 15:32-36). This went against the Law and He received the punishment of the Law, death. This is an extreme example but the point I am making is that the Law, which was put in place by angels, carried weight with God. So that each violation and disobedience received the prescribed punishment, how much more do you think you will be punished if you reject Jesus, the sole expression of God's glory? Hebrews reminds us, "It is a dreadful thing to fall into the hands of the living God" (Hebrews 10:31).
