REV 21:27

27 No one who is morally impure, no one who does things [that God considers] detestable, and no one who tells lies, will ever enter that city. Only those people whose names are written in the book of the [one who is like a] lamb {whose [names] the [one who is like a] lamb has written in his book}, [the names] of people who have [eternal] life, will be there.
