1 Peter 1:3 note 4
34 Regeneration, like redemption and justification, is an aspect of God's full salvation. Redemption and justification solve our problem with God and reconcile us to God; regeneration enlivens us with God's life, bringing us into a relationship of life, an organic union, with God. Hence, regeneration issues and results in a living hope. Such regeneration is accomplished through the resurrection of Christ from the dead. "The resurrection of Christ, bringing in life and the gift of the life-giving Spirit, is that which potentiates the new birth into a living hope" (Alford).
