I called a close friend who is an excellent teacher and Bible student and we talked it over for about 30 minutes, his solutions were not compelling either.
The problem is that there seems to be conflicting data. If one accepts the New Testament passages at face value it appears that God reneged on a covenant that He declared to be unbreakable. Since God is immutable that cannot be the answer.
So the basic ground rule is if there seems to be a conflict I am missing something and, or not understanding something correctly. It is me that is wrong, not the Word that is in conflict.
There are many heresies present in the Body today. It is my belief that most of them emerge from not dealing well with situations like this. Primarily forgetting the ground rule. The Word is not in conflict, I am not reading the data correctly.
