As Joshua is on the doorstep of conquest and victory he is confronted by the Commander of the armies of the Lord. In this interaction, Joshua might be expecting to get some battle strategies for the next mission, but instead, when he asks the angel what he is to do, he is told to take off his sandals because he was standing on holy ground. In taking off his sandals, Joshua was being invited to surrender his power, dignity and ownership, and God is still in the business of asking if we would be willing to surrender these things in our own life.
