Joshua is best known for leading the Israelites into the Promised Land after Moses' death and conquering it over seven years, making him one of the greatest military leaders in the Bible. However, the victories were due to God, not Joshua's skill. Joshua showed great faith in God by believing the Israelites could take the land despite its strong inhabitants, in contrast to the other spies. The primary lesson from Joshua is that God remains faithful to His promises to bring His people into the land He vowed to give them.
