Hello Ian,
You will note that nowhere in the extract that you quoted did I describe circumcision a a "physical sign".
With regard to your question, I'm not sure I understand it completely. You seem to have moved from the Abrahamic to the Davidic covenant. The Davidic covenant is not so different.
Psalm 89:28-9. 'My mercy I will keep for [David] forever, and My covenant shall stand firm with him. His seed also I will make to endure forever, and his throne as the days of Heaven.'
Now we know that David's son, Solomon succeeded to the throne of Israel, but that cannot be the fulfillment of the covenant since the succession of the Kings eventually failed. The fulfilment is in One greater than Solomon (Matt 12:42). David's true hope was not in a fleshly succession, but a spiritual; not in a son but a Saviour; not in the old covenant but the new; of which the Davidic covenant is an adumbration.
'Therefore my heart is glad and my glory rejoices; my flesh will also rest in hope. For you will not leave my soul in Sheol, nor will you allow Your Holy One to see corruption (Psalm 16:9-10. cf. Acts 2:25-36).
I'm not sure if this answers your question. If it doesn't, perhaps you would kindly re-phrase it?
With respect, I think your problem (if I may so phrase it) lies in confusing the old and new covenants. Of the old covenant it is written, 'Unless the LORD of hosts had left us a very small remnant, we would have become like Sodom, we would have been made like Gomorrah' (Isaiah 1:9. cf. Rom 11:5); of the new covenant, the Holy Spirit says, 'For all shall know Me, from the least of them to the greatest of them. For I will be merciful to their unrighteousness, and their sins and their lawless deeds I will remember no more' (Heb 8:11-12).
Every blessing,
Steve
