New Jerusalem is the imagery that is used to describe what will be at the center of the “new earth”. It is a reminder that all Christians will enjoy the blessings that were originally reserved for only the people of Israel. It is significant to contrast this city with Eden, as cities have been associated with the worst of humanity, but the new Jerusalem will be a redeemed perfect place. There will not be a temple, because through the presence of the Lord the role of a temple is fulfilled. This is some of the significance of the new Jerusalem as it is seen in the book of Revelation.
It is the place where all true believers will live. It represents the fulfillment of God’s plan for a place that His people can live in peace and harmony without fear, sickness, sorrow and anything that would be consequences of sin as sin will be eliminated.
The new Jerusalem is to be a city rather then a garden like what Adam and Eve had. This city is to be a cube that is over 2000 miles in every direction
Instead of splendid isolation (as in the garden) we will be in redeemed community (in the New Heaven and Earth). It has taken a real mind shift in my life to come to appreciate this.
The New Jerusalem, with its splendour and glory, stand in contrast to the garden of Eden. Both are a reality, that contradict any notion that the after-life is not physical. The new Jerusalem is a city, which will be inhabited by the redeemed. It will not fall prey to temptation, because Christ has overcome sin. Instead there will be no pain or death, and, with God dwelling among His people, there will be everlasting holiness among the community.
It is where true believers will spend eternity with God.
