The concept of the “Book of Life” appears prominently in the Bible, especially in the context of final judgment. This theme is closely related to the doctrine of salvation and eternal destiny. In the final judgment scenes described in Revelation, other books are also mentioned alongside the Book of Life, which are used to judge the deeds of all people.
The eyes of the Lord are on the righteous and his ears are attentive to their cry.
Psalm 34:15 (NIV)
