Revelation 21:27 (KJV)

What does Revelation 21:27 mean?

Revelation 21:27 says that nothing impure, shameful, or deceitful will ever be allowed to enter the New Jerusalem, but only those whose names are written in the Lamb’s book of life. This verse draws a clear line between those who belong to God and those who do not, emphasizing the absolute purity of God’s eternal city.

The speaker is John, describing his vision of the New Jerusalem at the end of Revelation. He is writing to early Christian communities, painting a picture of the future dwelling place of God with His people. The verse highlights that entry into this city is not based on human effort or status, but on being recorded in the Lamb’s book of life—a symbol for those who truly belong to Christ.
