"From the greatness of the crisis and the solemnity of the warning, these emissaries must be creatures of awesome power. Yet they seem unaccountably crude, uncouth, and unseemly. They surprise us. “Frogs!” we exclaim, “heralds of battle? Ambassadors to kings? Impossible! Absurd! Ridiculous!” The crisis is the greatest in the annals of war. It is referred to in scripture, as well as in our text, as “the battle of that great day of God Almighty.” It is portrayed as a World War, a Universal Conflict. And yet — to assemble the militant nations — three slimy batrachian monsters! What are these “questionable shapes,” these disgusting amphibia, from the swamps and mud of dried-up Euphrates? John describes them as “unclean spirits,” they are “demons,” or dead men. What we see in the vision is three ghostly emissaries, one out of the mouth of each of the confederates, the dragon, the wild beast, and the false prophet — gigantic shadowy frogs, croaking night prowlers, cold-blooded reptiles dwelling in marshes, quagmires, and stagnant waters, with their spotted skin, their sprawling limbs, their agile leap, their dismal croakings filling the night with noise. They are as politicians, these masqueraders, at home in the slimy pool, in the gooey mud, in the air or on solid ground; noisome, repulsive, abhorrent. Of what are these cheap orators, these uncanny imposters the emblem?"

"The truth is, my beloved, you can be filled with the Holy Spirit or you can be filled with the spirit of the devil. You can be filled with God’s Spirit or you can be filled with the spirit of the world. You can be filled with the Spirit of Christ or you can be filled with religious spirits. You can be filled with the spirits of demons, devils, and evil spirits. I don’t care how you conjure them up. Matters not to me whether you think they are entities walking about in the invisible spirit world about you or whether they are something that comes out of a state of mind — these powers are real and Jesus cast them out of people. I don’t pretend to understand all about evil spirits — I don’t even understand all about the Holy Spirit and how He works! And I am much more interested in the Holy Spirit than I am in a devil or a demon or an evil spirit. I’m not a devil preacher. I am not devil conscious in my own life. But it is a fact that there is an unclean and evil anointing just as there is an anointing of the Holy Spirit! And every man who follows on to know the Lord will eventually come face to face with every one of those unclean “anointings” or “devils” when he comes to his Armageddon; for Armageddon is the final battle where Babylon, with all its carnality, worldliness, fleshliness, deception, and deviltry falls to rise no more. Therefore this battle must of necessity deal thoroughly and eternally with every one of the “spirits of devils’! Armageddon is where all the devilish spirits, all the worldly spirits, and all the religious spirits make their last stand against the Lord of hosts! And, like General Custer, they go down into ignominious and everlasting defeat! IT IS THE BATTLE OF THE GREAT DAY OF GOD ALMIGHTY!"
