If you could read a book containing all that has happened and will ever happen in your life, would you? If you choose to read it, you must read it cover to cover.
I would not want such a book that laid out every step of my life. One of the joys of life is the unexpected events that God chooses to bless your existence. I have practiced living by faith in the three decades since choosing to live a life centered on Christ. Accepting such a book would go against the beliefs I hold so dear. My belief is that God will afford me the grace to accept whatever befalls me, the strength to overcome and the appreciation to know what my blessings are.
Fear of the unknown worries many people. This kind of book could take away the fear of the unknown, but it would quickly be replaced by fear of the known. There is nothing in the prompt to suggest the future could be changed to avoid the bad, so I see no reason for knowing.
