What does the Bible say about eternal justification?

Eternal justification is rooted in the understanding that God, who is immutable, considers His people justified in Christ from eternity. Ephesians 1:3-4 evidences this by stating that God chose us in Him before the foundation of the world to be holy and blameless. This view emphasizes that justification is not based on a temporal event, but on the unchanging nature of God's decree. Justification is therefore not a response to Christ’s death but predates it, illustrating God's eternal plan for redemption.
