The Heavenly Jerusalem is NOW

But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem and to myriads of angels. Hebrews 12:22

Hebrews 18-24 contrasts Sinai and Zion or the old covenant and the new covenant in a way that brings pictures of the old covenant such as blazing fires, darkness and gloom, Fear and trembling to that of the new covenant at Mount Zion with myriads of angels, Spirits of the righteous made perfect, sprinkled blood speaks better than the blood of Abel.

The Earthly Jerusalem was established in the law of Moses and this law was instituted with fear and trembling carrying fatal consequences for disobedience forged in blood. Abels blood cried out from the ground and resulted in vengeance. Yet the heavenly Jerusalem was established in blood and instead of screaming out for vengeance the blood of Jesus cries out for freedom.

The Christian is now enrolled into the church of the firstborn and his spirit is righteous having been made perfect. The only covenant of any meaning to the Christian is the one that Jesus is the mediator of. The Heavenly Jerusalem is forever established and held for us because our enrollment in this Heavenly Jerusalem is not kept on earth where it can be stolen but kept in heaven by Jesus.
