Joshua and the Israelites have just crossed over the Jordan River into the Promised Land—the land God had promised they would eventually settle in and become a nation. The first city that needed to be conquered was Jericho, and it was surrounded by a tall, thick, reinforced wall. The wall is what separated Joshua from his goal. In the same way, we all may face a wall of our own, and our walls separate us from our desired future—like a better marriage, quality friendships, or a healthy lifestyle.
