In our study of Revelation chapter twenty one, we are shown the place (bridal home) that Jesus promised us when He said that He was going to prepare a place for us.
"Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away, and there was no longer any sea." NIV translation
The apostle John continues to share the vision that he was given by Jesus Christ. In chapter twenty, we saw the marriage banquet and the judgment/removal of everything that does not belong in the presence of God. The next part of the traditional Jewish marriage is when the groom takes the bride to the home he has prepared for her. In this case, God is bringing the home to meet us.
The first difference we see between the old earth and the new is the absence of seas. There are those that say the earth is not big enough for everyone that has ever been born and accepted Jesus as their Lord and Savior. They will point to the fact that, even though the earth is large, it is still limited in the amount of available land.
Today, the earth is about 75% covered by the seas and oceans but on this new earth all of that land is no longer covered by water.
"I saw the Holy City, the new Jerusalem, coming down out of heaven from God, prepared as a bride beautifully dressed for her husband." NIV translation
There is much debate over who owns and controls the city of Jerusalem today as it has been claimed by Muslims as well as Jews & Christians. This verse shows us how God is going to settle the controversy. The simple fact of the matter is that the city has always been set aside by God for His people. While the different groups fight to control the city we see today, God has prepared a new city for His people (those who have accepted Jesus Christ as their Lord and Savior). While the city of today has many problems and much conflict, this new city will have the very glory (presence) of God.
