Joshua 1-7, Mark 16 Preparing for battle

In Joshua 1 the Lord has a talk with Joshua to prepare him for battle. What does our military do when we prepare for battle? I don't have any military experience but I know they go to boot camp and assumedly learn protocol for different situations, learn how to handle their weapons, study different strategies for war winning.

Joshua is told to prepare a different way. Joshua 1:7-8 says "Be strong and very courageous. Be careful to obey all the law my servant Moses gave you; do not turn from it to the right or to the left, than you may be successful wherever you go. 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."

Ironically, although the point he is making to Joshua is to be successful in whatever he does he needs to meditate on God's law, I was thinking in my head "Day and night? I like to study in the morning but if I did it at night too I wouldn't ever get to read anything else or do anything else." I can't believe that this is the thought I have while reading. Is that the thinking of a person training for a crown that lasts or is that trying to get by?

That's not the person that I want to be. I want to get my success through the Lord. I want to study his word so that I am careful to do everything that it says.

When Joshua fights against Jericho he does pray to God, but he also sends spies so that he can be prepared. God doesn't ask us to close our eyes and blindly follow him without using the brain we have been given. The Lord ultimately fought the battle for them, but they still fought prepared and carried out the instructions.
