God speaks; he has from the very beginning. Throughout history, he has guided his people by his Word. Moses warned Israel to listen to the Word of God and obey it. But he also predicted that a new prophet would arise who would be even greater and would carry a greater message. In Deuteronomy 18, Moses was pointing the Jesus, the greatest and final prophet, who brought God's Word to us in its fullness and offered us life everlasting.
