The Book of Life in Christianity and Judaism, (Hebrew: ספר החיים, transliterated Sefer HaChaim; Greek: βιβλίον τῆς ζωῆς Biblíon tēs Zōēs) is the book in which God records the names of every person who is destined for Heaven or the world to come. God has such a book, and to be blotted out of it signifies death. The Psalmist likewise speaks of the Book of Life in which only the names of the righteous are written and from which the unrighteous are blotted out.
The phrase “Book of Life” appears eight times in the New King James Version of the Bible, and seven of those are in the book of Revelation. As to who will be written in the book of life? The following verses give the answer:
“And there shall in no wise enter into it any thing that defileth, neither whatsoever worketh abomination, or maketh a lie: but they which are written in the Lamb’s book of life” (Revelation 21:27). And, “He who overcomes shall be clothed in white garments, and I will not blot out his name from the Book of Life; but I will confess his name before My Father and before His angels” (Revelation 3:5).
How can we be sure that our names are written in the Book of Life? First, we need to repent of our sins (Luke 13:3). Then, we need to “Believe in the Lord Jesus” (Acts 16:31). God has already done all of the work. All we must do is receive, in faith, the salvation He offers (Ephesians 2:8-9). We need to fully trust in Jesus alone as the payment for our sins. If we believe in Him, we will not perish (John 3:16).
Finally, we need to walk as Jesus walked in obedience to God’s moral Law (Exodus 20) by the power of His grace (Colossians 2:6). God supplies all the grace necessary to do that which is right for “all things are possible with God” (Mark 10:27).
