Rev 5:­2 "And I saw a strong angel proclaiming with a loud voice, Who is worthy to open the book, and to loose the seals thereof?"
Rev 5:­3 "And no man in heaven, nor in earth, neither under the earth, was able to open the book, neither to look thereon."

This must of been a magnificent site to see, all kinds of creatures from heaven and earth trying to open the seal but also a very sorrowful scene.

Rev 5:­4 "And I wept much, because no man was found worthy to open and to read the book, neither to look thereon."

This roll was written within and without. John says: "I wept much, because no man was found worthy to open and to read the book, neither to look thereon." The vision as presented to John made its impression upon his mind. The destiny of every nation was contained in that book. John was distressed at the utter inability of any human being or angelic intelligence to read the words, or even to look thereon. His soul was wrought up to such a point of agony and suspense that one of the strong angels had compassion on him, and laying his hand on him assuringly said, "Weep not: behold, the Lion of the tribe of Judah, the Root of David, hath prevailed to open the book, and to loose the seven seals thereof." {20MR 197.3}
