“Anyone not found written in the Book of Life was cast into the lake of fire” Revelation 20:15
This unambiguous statement was written by John as a description of what God was revealing to him. The purpose of the occasion was that John record this for people to read, understand, believe and act upon. If the statement is not true then God is a deceiver and not to be trusted. No wonder John wrote at the beginning of this book, “Blessed is he who reads and those who hear the words of this prophecy, and keep those things which are written in it; for the time is near” (Revelation 1:3).
Since the lake of fire is the destiny of all whose names are not in the Book of Life and only those whose names are in this Book will enter the new creation (Revelation 21:27) it is a matter of highest priority and greatest urgency for every person to be sure their name is in that Book.
In John 3:18 we read, “He who believes is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.” Twice in this verse it says that the dividing factor is faith in Jesus Christ. Everyone’s name is written in the “books” as condemned but upon exercising faith in Jesus Christ one’s name is written in the Book of Life. Jesus called this being “born again” (John 3:3, 7). Paul called it a “new creation” (2 Corinthians 5:17; Galatians 6:15).
Condemnation is God’s sentence upon sin and since condemnation came when Adam sinned we are all born in sin and “all have sinned” (Romans 3:23), all are condemned and God’s wrath abides on us. However, the one who believes is no longer condemned because he has trusted that Jesus Christ died for his sin (John 3:36; Romans 5:8; 8:1). This is the reason Jesus came (John 3:17).
Only in Jesus Christ can condemnation for sin be removed because He bore the sentence for our sin on the cross. Forgiveness of sin and deliverance from wrath is only through Jesus Christ who died in our place (Hebrews 9:22, 26-28).
Anyone who denies this truth reveals that their name is not yet in the Book of Life. Their destiny is the lake of fire but that is not God’s desired destiny for anyone. Jesus bore the sin of everyone so that all might be saved but only those who believe Him will have their names written in the Book of Life.
Again I write, this is of the highest priority and the most urgent concern to anyone who is not assured that their name is written in the Book of Life.
