Revelation 20:15

anyone not found written in the Book of Life was cast into the lake of fire
God is righteous and just. He will dutifully check the Book of Life for the name of each and every one who stands in this judgment. Scripture records the sober outcome: those not written in the book face eternal doom. Being “the resurrection of condemnation” (John John 5:39), none of these will be found written. The Beast worshipers in their midst—a relatively small proportion of the sum total of unbelievers of all ages—will never have been written in the book (Rev. Rev. 13:8+; Rev. 17:8+; see Beast Worshipers are Unique ). The rest of the unsaved dead were written in the book at one time, but having rejected God until their death, their names were blotted out (Ex. Ex. 32:32; Ps. Ps. 69:28; Rev. Rev. 3:5+).

Although their deeds determine the relative degree of punishment, all who reject the Lamb of God stand without atonement for their sin and are condemned. It is their absence from the Book of Life of the Lamb (Rev. Rev. 13:8+; Rev. 21:27+) which seals their fate and indicates a complete lack of relationship with Jesus—He never knew them (Mtt. Mat. 7:22-23):

He who believes in Him 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. (John John 3:18) [emphasis added]

He who believes and is baptized will be saved; but he who does not believe will be condemned. (Mark Mark 16:16) [emphasis added]

He who believes in the Son has everlasting life; and he who does not believe the Son shall not see life, but the wrath of God abides on him. (John John 3:36) [emphasis added]

And this is the testimony: that God has given us eternal life, and this life is in His Son. He who has the Son has life; he who does not have the Son of God does not have life. (1Jn. 1Jn. 5:11-12) [emphasis added]

The redeemed will be blessed with God’s intimate presence for eternity, but these go away into torment and eternal separation from all that is good—God. “These shall be punished with everlasting destruction from the presence of the Lord and from the glory of His power” (2Th. 2Th. 1:9).

Yes, O man! O woman! whoever you may be, your biography is written. An unerring hand has recorded every item, with every secret thing. There is not an ill thought, a mean act, a scene of wrong in all your history, a dirty transaction, a filthiness of speech, or a base feeling that ever found entertainment in your heart, but is there described in bold hand, by its true name, and set down to your account, to be then brought forth for final settlement, if not clean blotted out through faith in Christ’s blood before this present life of yours is ended.¹

And I say to you, My friends, do not be afraid of those who kill the body, and after that have no more that they can do. But I will show you whom you should fear: Fear Him who, after He has killed, has power to cast into hell; yes, I say to you, fear Him! (Luke Luke 12:4-5) [emphasis added]
