Revelation 13:8

Unbelievers around the world will not only serve Antichrist but also worship him. The "book of life of the Lamb" contains the names of God’s elect (cf. Daniel 12:1-2; Ephesians 1:4). Most if not all true believers will refrain from worshipping Antichrist (cf. Matthew 24:24). The long and unusual description of unbelievers in this verse has the effect of assuring believers during this time that they are indeed secure.
