"But at that time your people shall be delivered, everyone whose name shall be found written in the book."
The first time "the book" is mentioned in Scripture it is referred to as "your book." In Exodus 32, the day after the people worshiped the golden calf, Moses called the people together. He told them in verse 30, "You have sinned a great sin. And now I will go up to the LORD; perhaps I can make atonement for your sin." Moses asked God to forgive their sin, but if He would not "please blot me out of your book that you have written." He was offering himself as atonement for the people's sin. The LORD replied, "Whoever has sinned against me, I will blot out of my book."
David also refers to the book in Psalm 56:8, "You have kept count of my tossings; put my tears in your bottle. Are they not in your book?" In Psalm 69, a messianic psalm, verse 28 says, "Let them be blotted out of the book of the living, let them not be enrolled among the righteous."
Jesus alludes to the book in Luke 10, when the disciples were rejoicing saying "Lord, even the demons are subject to us in your name!" In verse 20, Jesus corrects their thinking, "Do not rejoice in this, that the spirits are subject to you, but rejoice that your names are written in heaven." Paul provides three specific names written in the book of life in Philippians 4:2-3. He says that Euodia, Syntyche, Clement and the rest of his fellow worker's names are in the book of life.
Revelation provides the most insight into the "book of life." In the letter to the church at Sardis in Revelation 3:5 Jesus says, "The one who conquers will be clothed thus in white garments, and I will never blot his name out of the book of life."
Revelation 13:8 expands the book's title to "the book of life of the Lamb." This verse also says the book was written before the foundation of the world. Those whose names are not written in the book of life are described as those who worship the beast.
Revelation 20:11-15 provides John's vision of the great white throne judgment. When the books are opened, one is the book of life. The dead are judged based upon what they have done from these books. Anyone whose name is not found in the book of life is thrown into the lake of fire.
Inevitably, when I think of judgment and the book of life, my mind goes to John 6 where Jesus fed the 5,000. The morning after their heavenly meal, the people want Jesus to feed them again. Knowing they are merely interested in physical food, He directs them to desire the food that provides eternal life. Their response is "Sir, give us this bread always." To which Jesus replies, "I am the bread of life; whoever comes to me shall not hunger, and whoever believes in me shall never thirst. But I said to you that you have seen me and yet do not believe."
Jesus then makes one of the most comforting statements in all of Scripture to those who believe: "All that the Father gives me will come to me, and whoever comes to me I will never cast out. For I have come down from heaven...to do the will of him who sent me...that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day."
Those who the Father gave to the Son, those whose names are written in the Lamb's book of life before the foundation of the world, will come to Him and He will raise them up on that day! He will lose nothing of all the Father gave Him!
Thank You, Lord Jesus. You are the bread of life, the true Bread which the Father gives. I rejoice along with my brothers and sisters who You will not forget; those You have engraved on the palms of Your hands.
