2 Bible Verses about Books, Metaphorical Use

Then I saw a great, white throne and Him who was seated on it [i.e., probably Christ]. Earth and heaven fled from His presence and they were not found anywhere [again]. And I saw dead people, the most important and the least significant ones, standing in front of the throne, and books were opened. Then another book was opened, which is the book of life [Note: This refers to a record of those to whom God has granted never ending life]. And these dead people [i.e., who have now been resurrected] were judged according to their deeds, based on what was recorded in the books.

So, I went to the angel and asked him to give me the little book. And he said to me, "Take it and eat it; it will be sweet as honey to your taste, but will cause you to have a sour stomach." So, I took the little book from the angel's hand and ate it. And [sure enough], it was sweet as honey to my taste, but after eating it, it gave me a sour stomach.
