Revelation 4-5 John had an amazing vision of heaven: "a throne, with one seated on it." This answered the question of his persecuted readers concerning who was in charge of the world. He also saw a "Lamb" standing as though it had been slain," but which is also called "the Lion of the Tribe of Judah." Only the Lamb was able to open the scroll which was in God's right hand. All the while, worship was taking place!
