"But Now" is yer Waterloo, Napoleon. You've worked very hard to "prove" a point of "Time Past" and if you were Israel and part of the Kingdom promises, I would say KUDOS to you. But alas. You're a mere neither Jew nor Gentile, dead in your sins, who is working hard to find salvation in the Jewish Kingdom. Rejecting the gospel of your salvation for the gospel for the Nation Israel. "Dispensational Envy" is an effort in futility. And a complete waste of time. Since you cannot go back to "time past". And you cannot go forward to the "ages to come". It's "But Now" or nothing.
Ephesians 2:11-13. And 2 Tim. 2:15.
Paul answers this dipensational nonsense best in Galatians 3:23-29.
and btw, since i am a Christian, i am part of the “Israel of God”
Rom. 3:21
