Do not fear what you are about to suffer. Behold, the devil is about to throw some of you into prison, that you may be tested, and for ten days you will have tribulation. Be faithful unto death, and I will give you the crown of life.
This artwork describes the new Jerusalem mentioned in the book of Revelation. The river was flowing from the throne of God and on each side of the river stood the tree of life yielding twelve different fruits every month. The city walls were decorated with twelve precious stones and with twelve gates remembering the sons of Jacob.
