The Scroll, Worship, Mission & Judgment - Rev. 5

What is the Scroll in God's Right Hand? Why is it so important? Why is John crying convulsively? How does the Scroll relate to Adam & Eve and to the Culmination of the Great Commission? Why is Lion of the Tribe of Judah, the Lamb of God, the only One who can take the Scroll and Open its 7 Seals? Why does this even matter?
