Is there another book greater than the Bible? No, but the Bible speaks of a great book both in the Old and New Testaments. While the Bible is the written word of God that no one must add or subtract from, the Book of Life still gets updated by the Lord Jesus. Now the Book of Life is a record of all those righteous before the Lord God who will not be punished in the Final Judgement and will therefore escape it. The Book of life and the Bible do NOT compete with each other but rather they complement each other. The main difference is that the Bible teaches us the principles of the Christian faith while the Book of Life is the record of those who are faithful to the Lord God.
The church in the current age must keep reminding itself that the Book of Life is to be held with great honor. I’m surprised that not many people in the church are aware of it. If you honor the teachings of the Bible then you automatically honor the Book of Life, even if you never knew of it’s existence till now. There’s nothing too mysterious about this. All you need to do is to search for it in the Bible.
Is the Book of Life a new teaching?
No, as the Book of Life has been mentioned even in the Old Testament. Let’s read the following:
So Moses went back to the Lord and said, “Oh, what a great sin these people have committed! They have made themselves gods of gold. But now, please forgive their sin—but if not, then blot me out of the book you have written.” The Lord replied to Moses, “Whoever has sinned against me I will blot out of my book. (Exodus 32:31-33)
For they persecute him whom you have struck down, and they recount the pain of those you have wounded. Add to them punishment upon punishment; may they have no acquittal from you. Let them be blotted out of the book of the living; let them not be enrolled among the righteous. (Psalm 69: 26-28)
The Lord God records the life and struggles of his people in the Book of Life. He remembers them all.
You have kept count of my tossings; put my tears in your bottle. Are they not in your book? (Psalm 56:8)
Then those who feared the LORD spoke with one another. The LORD paid attention and heard them, and a book of remembrance was written before him of those who feared the LORD and esteemed his name. (Malachi 3:16)
Your eyes saw my unformed substance; in your book were written, every one of them, the days that were formed for me, when as yet there was none of them. (Psalm 139:16)
Jesus himself spoke of the Book of Life even when he was on his mission on Earth and also later he spoke of it in heaven.
The seventy-two returned with joy, saying, “Lord, even the demons are subject to us in your name!” And he said to them, “I saw Satan fall like lightning from heaven. Behold, I have given you authority to tread on serpents and scorpions, and over all the power of the enemy, and nothing shall hurt you. Nevertheless, do not rejoice in this, that the spirits are subject to you, but rejoice that your names are written in heaven.” (Luke 10:17-20)
The one who conquers will be clothed thus in white garments, and I will never blot his name out of the book of life. I will confess his name before my Father and before his angels. (Revelation 3:5)
The context of the Book of Life is related to being faithful to God despite the tribulations of life.
At that time shall arise Michael, the great prince who has charge of your people. And there shall be a time of trouble, such as never has been since there was a nation till that time. But at that time your people shall be delivered, everyone whose name shall be found written in the book. (Daniel 12:1)
The Book of Life is linked to prophecy and the Final Judgement
The beast that you saw was, and is not, and is about to rise from the bottomless pit and go to destruction. And the dwellers on earth whose names have not been written in the book of life from the foundation of the world will marvel to see the beast, because it was and is not and is to come. (Revelation 17:8)
Then I saw a great white throne and him who was seated on it. From his presence earth and sky fled away, and no place was found for them. And I saw the dead, great and small, standing before the throne, and books were opened. Then another book was opened, which is the book of life. And the dead were judged by what was written in the books, according to what they had done. And the sea gave up the dead who were in it, Death and Hades gave up the dead who were in them, and they were judged, each one of them, according to what they had done. Then Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire. And if anyone’s name was not found written in the book of life, he was thrown into the lake of fire. (Revelation 20:11-15)
Only those who have their names written in the Book of Life will be allowed in the new Jerusalem of the future, which is the inheritance of those who believe in the Lord God.
But nothing unclean will ever enter it, nor anyone who does what is detestable or false, but only those who are written in the Lamb’s book of life. (Revelation 21:27)
Those who add or remove from the Scriptures are warned very clearly about their status in the Book of Life.
For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book: And 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, and from the things which are written in this book. (Revelation 22:18-19)
What to do so that one’s name always remains in the Book of Life?
You need to believe in the Lord Jesus and repent of your sins if you still into sinning. Romans 6:23 says that; For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.
Whoever believes in the Son has eternal life; whoever does not obey the Son shall not see life, but the wrath of God remains on him. (John 3:36)
You need to realize that you can either remain in Christ or remain in sin but never be in both. Ephesians 5:5 says that; For you may be sure of this, that everyone who is sexually immoral or impure, or who is covetous (that is, an idolater), has no inheritance in the kingdom of Christ and God.
You cannot earn the grace of God, you simply need to believe in the Lord Jesus for your salvation. Ephesians 2:8-9 says that; For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast.
