God picks up a book with seven seals binding it shut. Suddenly an angel starts shrieking Who is worthy to
open the book, and to loose the seals thereof? (v. 2) No one can, which causes John to cry. One of the old dudes in the chairs assures him that Jesus can open the book.
Next, a dead lamb appears in the middle of the floor. It has seven horns and seven eyes, because it represents the seven spirits of god. It takes the book and the old dudes and the animals all start worshiping it. Now they have harps and censers and they sing about Jesus and the book.
John realises that there are more things in the room as millions of angels and animals, then everything on earth starts shouting about Jesus. Then the original four animals say amen.
The Jesus lamb starts opening the seals on the book. The first one causes a man with a bow to appear, riding a white horse. They put a crown on him and he rides off to conquer stuff. The second horse is red and its rider has a sword. He gallops off to take away peace on earth and make people kill each other. The third rider is on a black horse and has a set of balancing scales. He babbles for a bit about the price of wheat and reminds us not to overdo it on the wine or oil. The fourth horse is pale (v. 8) and is being ridden by Death, with Hell following along behind. Death is given charge of a quarter of the earth and is allowed to kill people by the sword, famine or wild beasts. When the fifth seal is opened, John sees a bunch of martyred souls under the altar shrieking about vengeance. They are handed white robes and told it will be a while yet, but to hang tight until their brethren are similarly killed. The sixth seal causes a massive earthquake and solar eclipse and the moon turns crimson. The stars fall down and the figs die. Heaven rolls up and the mountains and islands all take one step to the left. The people hide and beg the mountains to give them shelter from the wrath of god.
