@AlfredEPH413 John 3 vs 18... believing in the lamb automatically puts you in the Lamb's book which is the book of life
The book of work proved their guilt but the Lamb's book determined their destiny.
@AlfredEPH413 They were judged based on the book of life and not of works because in Romans 3 vs 20, noone is justified in God's eye by works of the law .. so it had to be by faith through the belief in Christ which brings eternal life by putting their name in the book of life .
