I like you as a person, but no theology will "grow on me" that throws out three books of the New Testament for the millennium or the Jews. Not now, not tomorrow, not next year, not in the millennium, not in heaven, NEVER!
I don't throw them out . . . I just understand that the primary audience are to believers that were saved under the Jewish economy. Abraham was saved, just as Paul shows . . .
"What shall we say then that Abraham our father, as pertaining to the flesh, hath found? For if Abraham were justified by works, he hath whereof to glory; but not before God. For what saith the scripture? Abraham believed God, and it was counted unto him for righteousness. Now to him that worketh is the reward not reckoned of grace, but of debt. But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness" (Romans 4:1-5).
He was saved but it was a covenant that had to be maintained by the believer through sacrifices, gifts and offerings prescribed by Moses. In the Old Testament Judaism was a works-based religion.
"Wherefore then serveth the law? It was added because of transgressions, till the seed should come to whom the promise was made; and it was ordained by angels in the hand of a mediator. Now a mediator is not a mediator of one, but God is one. Is the law then against the promises of God? God forbid: for if there had been a law given which could have given life, verily righteousness should have been by the law. But the scripture hath concluded all under sin, that the promise by faith of Jesus Christ might be given to them that believe.
But before faith came, we were kept under the law, shut up unto the faith which should afterwards be revealed" (Galatians 3:19-23).
