The Book of Life
The Book of Life is a record written by God before He created the world. It lists those who will live in heaven. You can ensure that your name is there, through faith.
3And I intreat thee also, true yokefellow, help those women which laboured with me in the gospel, with Clement also, and with other my fellowlabourers, whose names are in the book of life. – Philippians 4:3
