War is conducted on the understanding that the Lord, not the Hebrews, will be the cause of victory. Only a small number of loyal soldiers are required. Finally, the religious culture of Deuteronomy and the Gospel is discussed. The culture is different from, and sometimes irreconcilible with, typical modern American sensibilities. God is to be uncompromisingly trusted and obeyed. Yet He loves and desires to have mercy on us, that we may love Him in return. This is not a tolerance for sin, but a reminder of the gravity of his forgiveness.
