What does the Bible say about lambs book of life?

Bible Topic · WEB

The Bible teaches that the Lamb's Book of Life contains the names of those who belong to Jesus Christ and will receive eternal life in God's holy kingdom. Revelation 13:8 and 17:8 connect this book with God's saving purpose from before the foundation of the world, humbling believers before His sovereign grace. Revelation 21:27 declares that only those written in the Lamb's book may enter the new Jerusalem, while Revelation 20:12, 15 warns of final judgment for those not found there. Yet Christ comforts His people: Revelation 3:5 promises that He will never blot out the overcomer's name, and Luke 10:20 calls disciples to rejoice that their names are written in heaven.
