“In a real though figurative sense, the book of life is the record of the acts of men as such is written in their own bodies. It is the record engraven on the very bones, sinews, and flesh of the mortal body. That is, every thought, word, and deed has an effect on the human body; all these leave their marks, marks which can be read by Him who is Eternal as easily as the words in a book can be read” (McConkie, Mormon Doctrine, 97).
