Although Joshua 11 does not record any miracles, the power of God is the key motivating factor behind Joshua’s actions (Joshua 11:6). In particular, Joshua's knowledge that the Lord is in complete control is what encourages Joshua not to fear.

In light of the great horde of enemy forces, it would have been natural for Joshua and Israel to be afraid. Imagine yourself in their position. You hear about this impressive alliance, spies report that there are thousands of soldiers gathering together on their way to kill you. If you leave the camp to go and meet them in battle, your wife and children will have no one to protect them. Marching into battle is a march into certain death unless the Lord intervenes. You are being called to risk your life in obedience to God. We must remember as we read from the Book of Joshua, that Joshua and the rest of the Israelites were real people. They had wives whom they loved and cared for. They had children and livestock. They were not immune to fear and doubts. Trusting in God’s Word of promise did not come naturally to them, it wasn’t easy for them to walk by faith.

The Lord reminds Joshua of his sovereignty and that he is fighting on behalf of Israel. Joshua needs to hear God’s promises so that he can have the courage to obey God. The words Do not fear are an encouragement that is repeated throughout Joshua (Joshua 1:9;  Joshua 8:1; Joshua 10:8; Joshua 11:6).
