“He that overcometh, the same shall be clothed in white raiment; and I will not blot out his name out of the book of life, but I will confess his name before my Father, and before his angels.” -Revelation 3:5
What is the Book of Life?
In Revelation 13:8 we see that those whose names are not written in the Book of Life shall worship the beast. We also see the fuller name or a description of the Book of Life; “…the book of life of the Lamb slain from the foundation of the world.”
In Revelation 17:8 we see that those whose names are not written in the Book of Life shall wonder when they behold the beast. We all so see the Book of Life described as “the book of life from the foundation of the world”
In Revelation 20:15 we see that “…whosoever was not found written in the book of life was cast into the lake of fire.”
In Revelation 21:27 we see that “…they which are written in the Lamb's book of life” shall enter the Holy and New Jerusalem (which is the Lamb’s wife and bride, the true Church, the true Israel). (See Revelation 21:1-2, Revelation 21:9-10, Colossians 1:24, Ephesians 5:23-32, 2 Corinthians 11:2, Revelation 19:7-9,Matthew 9:15, Romans 2:28-29, Romans 9:3-33)
We see in Revelation 22:19 that “…if any man shall take away from the words of the book of this prophecy, God shall take away his part out of the book of life, and out of the holy city…”
Now this Book of Life is not just mentioned in the New Testament.
In Exodus 32:31-33 we see Moses pleading to God to forgive the people of their great sin. Moses says unto God “Yet now, if thou wilt forgive their sin--; and if not, blot me, I pray thee, out of thy book which thou hast written. And the LORD said unto Moses, Whosoever hath sinned against me, him will I blot out of my book.”
In Daniel 12:1 we read that “there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, every one that shall be found written in the book.” The Book of Life may also be alluded to in Psalm 139:16.
Let us rejoice that we have life through Christ!
“Much more then, being now justified by his blood, we shall be saved from wrath through him. For if, when we were enemies, we were reconciled to God by the death of his Son, much more, being reconciled, we shall be saved by his life. And not only so, but we also joy in God through our Lord Jesus Christ, by whom we have now received the atonement.” - Romans 5:9-11
“The LORD thy God in the midst of thee is mighty; he will save, he will rejoice over thee with joy; he will rest in his love, he will joy over thee with singing.” - Zephaniah 3:17
