What does the Bible say about God's book of life?

The concept of God's book, often referred to as the Book of Life, is strongly emphasized in Scripture. For instance, Daniel 12:1 states that those whose names are found written in this book will be delivered. Revelation 5 highlights that only Christ is worthy to open this book, and it contains the names of God's elect, those predestined for salvation before the foundation of the world. This divine record underscores God's sovereignty, demonstrating that salvation is not based on human merit but solely on God's choice. The assurance that one's name is written in this book serves as a profound comfort to believers, affirming their security in Christ's redemptive work.
