Hi ha ha I like your comment. Unfortunately, only the Christ has this book since it belongs only to him. The Book of Life is just an example to humans that can explain how God remembers people that have always been right in their hearts even from the beginning and have been a long time dead. God never forgets how he observes each one trying to “follow” him. The memory of God is not like humans when he could possibly forget something or can't remember something that he has already decided. I would not worry about it; your name won’t be missed if you have done the best you can. But remember this even if we should commit a sin, we have the sacrifice to “cover over” our mistakes. So, rest your mind and have peace.
1 John 2:1-4
Living Bible
2 My little children, I am telling you this so that you will stay away from sin. But if you sin, there is someone to plead for you before the Father. His name is Jesus Christ, the one who is all that is good and who pleases God completely. 2 He is the one who took God’s wrath against our sins upon himself and brought us into fellowship with God; and he is the forgiveness for our sins, and not only ours but all the world’s.
3 And how can we be sure that we belong to him? By looking within ourselves: are we really trying to do what he wants us to?
4 Someone may say, “I am a Christian; I am on my way to heaven; I belong to Christ.” But if he doesn’t do what Christ tells him to, he is a liar.
