"The priests, under the old covenant, performed their ministry in relationship to the Ten Commandments. So, Jesus Christ our high priest, now in heaven, under the new covenant performs His ministry in relation to these same Ten Commandments; the original law of God.
We read in Hebrews 8:8-10: ...Now notice this– “For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people.”
You notice God did not say, “I will abolish my covenant, and give you a new law.” and neither did He say, “I will give grace to supersede the Ten Commandments.”
What God is really trying to tell us is that because of His grace, He will write His law in our hearts, and bring our lives into conformity to His precepts. Isn’t that simple?"
