Revelation 21:25-27

25Nobody will ever shut the city's gates at the end of the day. It will always be day and there will be no night there.

26People from all the world's nations will bring their beautiful and valuable things into the city.

27But nothing that is bad or unclean will ever go in there. Nobody who does anything that God hates will go into the city. Nobody who tells lies will go in. Only those people with their names written in the Lamb's book of life can go in there.
