Hope you don't mind if I add context back into the verses you quoted
Hebrews 8:7 For if that first
covenant had been faultless, then no place would have been sought for a second.
8 Because finding fault with them, He says: “Behold, the days are coming, says the Lord, when I will make a new covenant with the house of Israel and with the house of Judah— 9 not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt;
because they did not continue in My covenant, and I disregarded them, says the Lord. 10
For this is the covenant that I will make with the house of Israel after those days, says the Lord: I will put My laws in their mind and write them on their hearts; and I will be their God, and they shall be My people. 11 None of them shall teach his neighbor, and none his brother, saying, ‘Know the Lord,’ for all shall know Me, from the least of them to the greatest of them. 12 For I will be merciful to their unrighteousness, and their sins [
b]and their lawless deeds I will remember no more.”
We are so blessed to have a Savior who is longsuffering and loving. The old covenant (agreement) was broken because the fault was
in the people, not His perfect and holy laws Psa 19:7 Rom 7:12,
they broke the agreement by disobeying God. God is not doing away with His holy law and now we can worship other gods, vain His holy name bow to idols, covet murder etc. The old covenant (agreement) was based on the people doing, the New Covenant (agreement) is based on God doing.
He writes His holy law in our hearts and minds all we need to do in not change our minds and cooperate. It says nothing about different laws, one would have to add that to the Text to make this argument.
Amen! All authority is given to Jesus and no man has the authority to change anything from His holy law which is why Jesus warns us not to break or teach others to break the least of the commandments Mat 5:19-30
You seem to be adding words that are not found in the Text. Can you point the law that is being changed of the priesthood in Hebrews 7 is the Ten Commandments. The law that is being changed is the
priesthood. Hebrews 7:28 No longer do we have to go to a human priest and present a sacrificial offering for sin. In the New Covenant Jesus is now our High Priest Hebrews 4:14-16 Heb 7:28 and instead of sacrificing animals for our sins, we can go directly to our High Priest who became the Sacrificial Lamb 1 Cor 5:7 Hebrews 10:1-10 so we can go directly to Jesus for the forgiveness of sins when we repent 1 John 1:9 which means a change in our direction. Sin is still breaking the Ten Commandments Romans 7:7 even in the NT breaking one you break all James 2:10-12 The Ten Commandments is so we can "see" our sins Romans 3:20 and shows our need for Jesus, so we can go to Him when we are truly sorry for forgiveness and sanctification and receive His mercy and grace. If we cover our sins, one cannot prosper Pro 28:13
No difference, the same commandments. Jesus is our example to follow 1 John 2:6 He didn't lead by example so we could do something entirely different. Hebrews 4:15 Jesus in facts says when we keep our rules over the commandments of God quoting directly from the Ten, He says our hearts are far from Him Mat 15:8 (opposite of the New Covenant Heb 8:10) and one worships in vain. Mark 7:7-8 Mat 15:3-9 we are called to worship Him in Truth and Spirit John 4:23-24 and if false (in vain) worship is breaking the commandments of God, true worship is keeping the commandments of God Rev 14:12 as no man has authority to change what He both wrote and spoke Exo 31:18 Ex 32:16 and is kept in His holy Temple under His mercy seat that is revealed in heaven Rev 11:19 and what the earthy temple was patterned after Heb 8:1-5 to show us the plan of salvation. Our salvation is from sin Mat 1:21 not in sin and through Jesus we can overcome and obey Him through faith and love 1 John 5:3 Romans 3:31 Rev 14:12 John 14:15 Exo 20:6
