CLAIM: The fullness of this passage speaks of the glory of Jerusalem and the Jewish people, who are physically and spiritually (born again) in Zion, during the Millennial Kingdom. This register is described in Hebrews 12:23, pointing to the born-again Jewish people registered in the heavenly Jerusalem (Heb. 12:23).
False.
Applies to Israel first, and then the church age. No need to go further.
