A fortress, a ghetto, and a tent
6 Be strong and courageous, for you shall cause this people to inherit the land that I swore to their fathers to give them. 7 Only be strong and very courageous, being careful to do according to all the law that Moses my servant commanded you. Do not turn from it to the right hand or to the left, that you may have good success[a]wherever you go. 8 This Book of the Law shall not depart from your mouth, but you shall meditate on it day and night, so that you may be careful to do according to all that is written in it. For then you will make your way prosperous, and then you will have good success. 9 Have I not commanded you? Be strong and courageous.Do not be frightened, and do not be dismayed, for the Lord your God is with you wherever you go.”
Three lessons to learn from Jericho, Ai, and Achan's tent
1) God fights for us if we are consecrated unto Him - our lack of skill and ability is not an issue
2) When you sin or fail morally, don't let the weight of your guilt cause you to despair.
3) God wants us to consecrate ourselves and eliminate specific sins from our lives
