Through studying the conquest of the Canaanite cities, the division of the land and the last days of Joshua, we learn some valuable lessons: Obey God, even if you don’t understand His will. Sometimes, God will give us a strategy to overcome; at other times, He just requires obedience.
The second lesson is to eradicate secret sin. Like the cities the Israelites did not conquer, sins we leave unsettled will become problems in our lives. This is how we can enter the Promised Land.
