Revelation 21:25-27

21:25 Its gates will never be closed during the day (and there will be no night there). 21:26 They will bring the grandeur and the wealth of the nations into it, 21:27 but nothing ritually unclean will ever enter into it, nor anyone who does what is detestable or practices falsehood, but only those whose names are written in the Lamb’s book of life.
