Assuming the Ten Commandments were "engraved in letters on stone", the Apostle has this to say about them. They were the transitory ministry that brought condemnation and death that has no glory now. The letter kills. Other than that, he thought they were pretty swell. - lol
With that in mind, why would I want anything to do with them?
2 Corinthians 3:6-11
He has made us competent as ministers of a new covenant—not of the letter but of the Spirit; for the letter kills, but the Spirit gives life. 7 Now if the ministry that brought death, which was engraved in letters on stone, came with glory, so that the Israelites could not look steadily at the face of Moses because of its glory, transitory though it was, 8 will not the ministry of the Spirit be even more glorious? 9 If the ministry that brought condemnation was glorious, how much more glorious is the ministry that brings righteousness! 10 For what was glorious has no glory now in comparison with the surpassing glory. 11 And if what was transitory came with glory, how much greater is the glory of that which lasts!
When someone says "the law is the law" or "sin is sin" it begs the questions which laws, or which sins.
So when you say "the law is the law" what are you trying to point out?
Though Paul is clear when read in context, there are many beliefs out there as you know. And some of them are false. Which ones?
1. That the Ten Commandments is the Law. (taught in many churches of all denominations).
2. That we are no longer under the law, so we are not condemned for sinning who believes Jesus paid the penalty. (Reformation)
3. We are no longer under the ceremonial laws, but are still under the Ten Commandments. (Seventh-day Adventists)
4. That the New Covenant is a different set of laws to keep. The law of the Spirit.
5. That the eternal law of God is to love God with all your heart, soul, and minds, and your neighbor as yourself
6. That we don't sin, so don't need the Ten Commandments? If so, why don't we sin?
a. They are no longer considered sins, because no law. (Nicolaitans)
b. The born again of the Spirit process gives us new natures that do not sin.
