Give me one reason why anyone should subject themselves to a completed and retired covenant having no jurisdiction.
Seems like I’m using the alphabet a lot with you lately. Let’s do it again.
A. Covenant is not synonomous with God’s Law. The Covenant is the agreement which contains God’s law, as well as blessings, curses, consequences, promises, stipulations, provisions and instructions.
B. Ironically enough the “New Covenant” in Jeremiah 31 and Hebrews 8 ALSO contains God’s Law, this time written on the hearts. So better luck ‘erasing’ God’s Law from the Covenants.
C. The only way you as a wild olive branch can claim ANY of the promises and covenants made between God and God’s People, is for you through Messiah to become grafted in AMONG God’s people. Outside of this you remain strangers to the covenants, excluded from the commonwealth of God’s Israel. (unless of course you use an eraser and remove the two houses written in Jer 31 and Heb 8 and put your own name in there)
D. So, yes, if you want to claim the New Covenant, make sure you are well aware that you are claiming that God’s Holy Law is written on your heart. That same Law that you are so SET on getting rid of.
It seems some want the salvation of the new covenant and then demand obligation the the law which is the ministration of death. Isn't one the subject of who or what they obey?
It seems that some want Messiah as their savior without being willing to make Messiah their Lord, choosing to NOT give up their own ways, their own will, their own plans, their own rules and celebrating their own man-made feasts, instead of walking in God’s ways, doing God’s Will, according to God’s plan, obeying God’s rules and celebrating His feasts.
I am indeed subject to who I obey, whether it’s sin unto death, or of obedience unto righteousness! I choose to obey God’s Law and Word which Paul tells us is righteous, holy, perfect, spiritual and good

(Romans 7:12)
