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

Assurance of being written in the Lamb's Book of Life is derived from understanding the profound grace of God in Christ. The Bible assures us that those who believe in the Lord Jesus Christ and depend on His work of salvation have their names written in this book. This assurance may come through recognizing the transformative power of faith in Christ, evidenced by a life that seeks to glorify Him and acknowledges total dependence on His grace, righteousness, and the cleansing of sins through His blood.
