Revelation 20:15 declares, “If anyone’s name was not found written in the book of life, he was thrown into the lake of fire.” The Book of Life, in this context, is the set of names of those who will live with God forever in heaven. It is the roll of those who are saved. This Book of Life is also mentioned in Revelation 3:5; 20:12; and Philippians 4:3. The same book is also called the Lamb’s Book of Life because it contains the names of those who have been redeemed by the blood of the Lord Jesus (Revelation 13:8; 21:27).
