The old covenant is that the chair is on one side of the room and the new covenant is that the chair is moved to the other side of the room.
Since we're using a familiar noun, we can remain with it for a while.
Hebrews 8 describes the old chair:
- The old chair is faulty: if that first covenant had been faultless, then no place would have been sought for a second.
- The old chair was violated, i.e. broken: they did not continue in My covenant.
- The old chair is obsolete: In that He says, “A new covenant, ” He has made the first obsolete.
- The old chair is ready for disposal: Now what is becoming obsolete and growing old is ready to vanish away.
Both Jeremiah 31 and Hebrews 8 contain a narrative of God making a new covenant, or a new chair, that
is not according to the pattern of the old chair: I will make a new covenant with the house of Israel and with the house of Judah - 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.
While you assert that moving the chair across the room somehow made it new (which is ubsurd), the narrative you're confronted with tells a entirely different story:
the old chair is disposed, and God made a new chair of an entirely different design.
The old covenant is that the law is written of stone and the new covenant is the law written on the heart.
Pretty simple...
I don't believe that I'm the first to break the news to you: Sinai
is according to Sinai, and God's promise is that He would write His "
My law" into His redeemed that
isn't according to Sinai.
Until you make this distinction that what (or rather, Who) has entered into us isn't from Sinai, you aren't going to make the smallest effort to determine what Scripture is telling us in its plain language.
