Yes, read the context of Hebrews 7 and the law its speaking of and why it had to change. I was quoting Heb 8 which is the change of the New Covenant. Heb 7 is about the priesthood law changing becuase the law said it had to come from the tribe of Levi but Jesus came from the tribe of Judah.
If we are God's people and are in a covenant with Him which including's having His laws written in our hearts the promises of the covenant is beautiful.
The agreement changed, which is what a covenant means, but God promised He would not alter the words of His covenant Psa89:34 why the NC is established on better promises and still has the law of God written in our hearts Heb8:10, if we cooperate with Him
THE LAW WAS CLEARLY CHANGED. If it hadn't been, there would have been no need for a change in priesthood. If it was intended to be the ten commandments (or any other law) , then the claim of the forgiveness of sins for those under the New Covenant, by being under the New Covenant, could simply not have been correctly made. The laws of the New Covenant to be logically consistent, be in conformance with, and supportive of Heb 8:12
