The elect are those chosen by God before the foundation of the world, whose names are written in the Lamb's book of life.
The doctrine of sovereign election is clearly illustrated in Ephesians 1, where it is said that God chose the elect in Christ before the foundation of the world for the purpose of holiness and blamelessness. This election is not based on any foreseen merit but on God's sovereign will and grace. The names of the elect are written in the Lamb's book of life, affirming their destined salvation and implying that all others, by virtue of their sin, are justly condemned, as indicated in Revelation 20:15.
