Moses began his farewell message to Israel with a reminder of their parents' refusal to obey God's word to enter the Promised Land. With his death, these Israelites will have to follow a leader other than Moses for the first time in their lives. Moses wants them to know that their real Leader hasn't changed. God had done mighty things for them in Moses' day. Now God will do mighty things in their day through Joshua. They will have more than second hand deliverance stories to tell their grandchildren. They will be eyewitnesses of God's power and faithfulness. But they would have to obey this same command their parents ignored and own a faith that their ancestors did not have!
