Question:
Are there any conditions in which your name can be removed from the Book of Life?

Answer:
No. Look at Revelation 3:5. “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.”

The overcomer is every true believer: “For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith (1 John 5:4). So the Lord assures believer in Christ: “I will not blot out his name out of the Book of Life.” What blessed assurance this is to every believer.
