“It must not be assumed that those who live in Jerusalem today without faith in Jesus have been chosen by God for salvation. Apart from repentance and faith, the inhabitants of Jerusalem continue to be in bondage and are ‘without hope and without God in the world’ (Eph. 2:12). To suggest anything else is to slight Jesus Christ and his sacrifice on the cross, while at the same time imperiling the souls of many by encouraging false presumption.
But there is another Jerusalem, a Jerusalem that is above, from which the enthroned Son of God sends forth his Spirit. Apart from this Jerusalem, none of us would have a mother to bring us into the realm of God’s redemptive work, for she is the mother of us all” (Gal. 4:26). Only those who have been born from above by the outpouring of the Spirit from the throne of Christ, situated in the heavenly Jerusalem, can claim to be citizens in the kingdom of God.”
