Be strong and courageous, because you will lead these people to inherit the land I swore to their forefathers to give them. Be strong and very courageous ... Have I not commanded you? Be strong and courageous. Do not be terrified; do not be discouraged, for the LORD your God will be with you wherever you go. (Joshua 1:6-7, 9)

Joshua knew what it was to be afraid. For years he had been second in command, Moses' right-hand man. But now it was his turn to lead. The children of Israel weren't just going to waltz in and pick up the Promised Land like a quart of milk; they were going to have to fight for it. And Moses was not going with them. If Joshua was completely confident about the situation, why would God have had to tell him over and over and over again not to be afraid? In fact, God gives him a special word of encouragement: "As I was with Moses, so I will be with you; I will never leave you nor forsake you" (Joshua 1:5). How was God "with Moses"? As a mighty warrior. Remember the plagues? Remember all those Egyptian soldiers drowned with their horses and chariots out there in the Red Sea? It was after that display of God's strength that the people of Israel sang, "The LORD is a warrior; the LORD is his name" (Ex. 15:3). God fought for Moses and for Israel; then he covenanted to Joshua to do the same, and they took down Jericho and every other enemy.
