What does the Bible say about names written in heaven?

In Luke 10:20, Jesus emphasizes the importance of rejoicing over one's name being written in heaven rather than any earthly achievements or powers. This concept underscores the idea of eternal life granted through God's grace to those He has chosen. The names written in heaven refer to those who have been electively chosen by God before the foundation of the world, as mentioned in Ephesians 1:4-5. It's a profound affirmation of the believer's identity in Christ, assuring them of their eternal salvation and the inseparable bond they have with their Savior.
