I knew that you had a strange notion of regeneration, but I didn't realize just how strange.Strange to you, in the same sense that the resurrection was to the ears of those blinded philosophers in Acts 17, as preached by Paul. Strange to people who reason outside of the scriptures, but clear truth to those enlighten by the Spirit of the Living God.
So then Red, under your Spirit enlightenment, is regeneration an exclusive feature of the New Covenant or was it always in place even under the Old Covenant as you suggested? Please forget about the derogatory remarks about being the same as the blinded philosophers in Acts 17. With respect I could refer those same words right back to you. But I don't.
By the way, I think you missed the real significance of Gal 4 concerning the son of Abraham. Paul is speaking there concerning the two different seeds of Abraham, the natural seed and the spiritual seed, ethnic Israel versus spiritual Israel. We are of spiritual Israel. And that has nothing to do whatever with our natural birth. Remember, Paul had just a few sentences earlier said,
Gal 3:28 There is neither Jew nor Greek, there is neither slave nor free man, there is neither male nor female; for you are all one in Christ Jesus.
Gal 3:29 And if you belong to Christ, then you are Abraham's descendants, heirs according to promise.
And it certainly has nothing to do with original sin or total depravity.
