God's new world gives us hope

Revelation 21:6-27
God is the Alpha and the Omega, the beginning and the end.
The second dead is to the people who are cowardly, unbelieving, the vile, ... their place will be in the fiery lake of burning fire.
There is not temple in the Holy City, Jerusalem, because the Lord God Almighty and the Lamb are its temple.
Only those whose names are written in the Lamb's book of life will enter it.
The bride of chapter 19 appears as a city: the new Jerusalem and its people. The finest cities of the world are nothing to the breathtaking splendour, the shining radiance, of this glowing, golden city, with its perfect dimensions, its jewelled foundations, its glittering diamond walls, its gates of pearl.
Those gates stand always open. And the city has no Temple, for God himself is present. There is peace here, and freedom and security.
1200 stadia: 2400km/1500 miles. It is 12x1000. On earth God's people seem few and scattered. But they are part of a vast community - the eternal city of God.
Why?
God is the beginning and the end. He has absolute authority, how can our be made could argue with him.
Only the  people without sin can enter the New Jerusalem city. His name is written in the Lamb's book of life. He who was believed the Jesus Christ and walk on his word.
John gave us the vision of our future, so all of the followers of Christ should stand firm on his word and bravely walk out and give honor to the Lord!
How?
Christian has honor personality and glory kingdom passport. Rejoice!
