How do we know our names are written in the Lamb's Book of Life?

Knowing that our names are written in the Lamb's Book of Life is a profound assurance stemming from God's sovereign grace. Ephesians 1:4-5 explains that believers were chosen in Christ before the foundation of the world. This truth should fill our hearts with joy, as it signifies that our salvation is rooted in God's eternal plan, not our merits. We can trust in our election as we are drawn to faith in Christ, demonstrating that our belief is a result of God's grace. This instills in us the confidence that our names will never be blotted out, as God's work in us is eternal and immutable.
