What are demons? Where do they come from? What are Hades and "the abyss" (sometimes translated as "the bottomless pit")? In this sermon Dr. Kayser explains some of the controversies around Revelation 9:1 ("So the fifth angel trumpeted, and I saw a ‘star’ that had fallen out of the sky to the earth. And to him was given the key to the shaft of the Abyss.") and explains the origins of angels and demons.
Dr. Kayser continues his exposition of the Fifth Trumpet in Revelation 9:1-12, going deeper into the theology of demons — Revelation's hints as to the scope of Satan's army, the authority of demons, the binding of demons in the pit, and more.
This sermon finishes the subject of the fifth trumpet, focusing upon the power, character, and activities of demons. The applications made to modern ecology and politics are just two of many practical applications.
