The Apostle John almost certainly knew the Lord Jesus more thoroughly than any of His other followers. When John wrote the gospel which bears his name, under the inspiration of the Spirit of God, he gave us a compelling defense of the deity of Jesus. As C. S. Lewis wrote, "Either this man was, and is, the Son of God: or else a madman or something worse..." In this Study Guide, Dr. Mellichamp shows how John used seven miracles Jesus performed and His seven "I am" claims to demonstrate conclusively the divinity of Jesus.
