God: "I looked for someone to take a stand for me, and stand in the gap" (Ezekiel 22:30)

Treat the book as a notepad with printed words. In other words, write in your books. Make the book your own by marking points of agreement and disagreement, highlighting particularly important sections of text, and underlining and diagraming where helpful. Unless your specific copy of the book has some historical or emotional value, mark it up with abandon.
