I did say that to deny the existence of evil spirits, or to deny the existence of the devil, is to deny the truth of the New Testament; and that to deny the existence of these imps of darkness is to contradict the words of Jesus Christ.I did say that if we give up the belief in devils we must give up the inspiration of the Old and New Testaments, and we must give up the divinity of Christ. Upon that declaration I stand, because if devils do not exist, then Jesus Christ was mistaken, or we have not in the New Testament a true account of what he said and of what he pretended to do.If the New Testament gives a true account of his words and pretended actions, then he did claim to cast out devils. That was his principal business. That was his certificate of divinity, casting out devils. That authenticated his mission and proved that he was superior to the hosts of darkness.Now, take the devil out of the New Testament, and you also take the veracity of Christ; with that veracity you take the divinity; with that divinity you take the atonement, and when you take the atonement, the great fabric known as Christianity becomes a shapeless ruin.The Christians now claim that Jesus was God. If he was God, of course the devil knew that fact, and yet, according to this account, the devil took the omnipotent God and placed him upon a pinnacle of the temple, and endeavored to induce him to dash himself against the earth…Think of it! The devil – the prince of sharpers – the king of cunning – the master of finesse, trying to bribe God with a grain of sand that belonged to God!Casting out devils was a certificate of divinity.Is there in all the religious literature of the world anything more grossly absurd than this?These devils, according to the Bible, were of various kinds – some could speak and hear, others were deaf and dumb. All could not be cast out in the same way. The deaf and dumb spirits were quite difficult to deal with. St. Mark tells of a gentleman who brought his son to Christ. The boy, it seems, was possessed of a dumb spirit, over which the disciples had no control. “Jesus said unto the spirit: ‘Thou dumb and deaf spirit, I charge thee come out of him, and enter no more into him.’” Whereupon, the deaf spirit (having heard what was said) cried out (being dumb) and immediately vacated the premises.The ease with which Christ controlled this deaf and dumb spirit excited the wonder of his disciples, and they asked him privately why they could not cast that spirit out. To whom he replied: “This kind can come forth by nothing but prayer and fasting.” Is there a Christian in the whole world who would believe such a story if found in any other book?The trouble is, these pious people shut up their reason, and then open their Bible.
