A friend recently posted a Facebook status update with the following verse.
"Have I not commanded you? Be strong and courageous. Do not be terrified; do not be discouraged, for the Lord your God will be with you wherever you go." Joshua 1:9
As I reflected on this, something struck me. Joshua hears these words as he is about to fight a very large battle entering into the Promised Land. So he hears what you might expect - be strong and have courage. But he is told to be strong and courageous for reasons that seem to have no direct connection to the battle.
He is told to be strong and courageous so that he might be obedient to the law - the commands and the ways of God (vv7-8). That is how success is defined.
Another reminder that while the battle is important, the kind of person entering the battle, to God, is at least as important.
