Do not let this Book of the Law depart from your mouth; meditate on it day and night, so that you may be careful to do everything written in it. Then you will be prosperous and successful. (Joshua 1:8)
As Ranger students we were told we could open the Ranger Handbook in any situation to get the answer. It's amazing how much information is in that little handbook. But what's even more amazing is how many Ranger students would completely ignore the book and wing it. You know God has given us a book with 99% of the answers. You aren't cheating if you open it up and look for guidance in the Bible. Life is an Open Book Test!
