I quote Bob: Deut 6:6 IS proclaiming the very heart of the new birth - of the changed heart - of the New Covenant. This is why there is only REALLY ONE Gospel.EQ
You identify the new birth - the changed heart - with the New Covenant, and make it 'the very heart' of the Gospel. "This is why there is only REALLY ONE Gospel", you wrote.
Bob, think of it, that Jesus Christ is the very heart of the New Covenant. I accept what have said, but your emphasis is wrongly placed on the subjective experience of very unreliable man, and the weight of your construction does not rest on the Sure Foundation - THE Only and Real Gospel, jesus Christ. The Gospel does not in the first place signify our proclamation of the Joyful Message - The Gospel is God's OWN Word of Good News, Jesus, Who was born in Bethlehem and reared in Nazareth, "Selected Acre" to God's Providence.
I have argued with you concerning the Law in the same way, so that we may keep God's Sabbath Day acceptable to Him, and not to His annoyance.
