• John 8:44-45
  You are of your father the devil, and the desires of your father you want to do. He was a murderer from the beginning, and does not stand in the truth, because there is no truth in him. When he speaks a lie, he speaks from his own resources, for he is a liar and the father of it. But because I tell the truth, you do not believe Me.
   
• 2 Thessalonians 2:9-12
  The coming of the lawless one is according to the working of Satan, with all power, signs, and lying wonders, and with all unrighteous deception among those who perish, because they did not receive the love of the truth, that they might be saved. And for this reason God will send them strong delusion, that they should believe the lie, that they all may be condemned who did not believe the truth but had pleasure in unrighteousness.
   
• Mark 5:1-9
  Then they came to the other side of the sea, to the country of the Gadarenes. And when He had come out of the boat, immediately there met Him out of the tombs a man with an unclean spirit, who had his dwelling among the tombs; and no one could bind him, not even with chains, because he had often been bound with shackles and chains. And the chains had been pulled apart by him, and the shackles broken in pieces; neither could anyone tame him. And always, night and day, he was in the mountains and in the tombs, crying out and cutting himself with stones. When he saw Jesus from afar, he ran and worshiped Him. And he cried out with a loud voice and said, “What have I to do with You, Jesus, Son of the Most High God? I implore You by God that You do not torment me.” For He said to him, "Come out of the man, unclean spirit!" Then He asked him, “What is your name?” And he answered, saying, “My name is Legion; for we are many.”
   
• 1 John 4:1-6
  Beloved, do not believe every spirit, but test the spirits, whether they are of God; because many false prophets have gone out into the world. By this you know the Spirit of God: Every spirit that confesses that Jesus Christ has come in the flesh is of God, and every spirit that does not confess that Jesus Christ has come in the flesh is not of God. And this is the spirit of the Antichrist, which you have heard was coming, and is now already in the world. You are of God, little children, and have overcome them, because He who is in you is greater than he who is in the world. They are of the world. Therefore they speak as of the world, and the world hears them. We are of God. He who knows God hears us; he who is not of God does not hear us. By this we know the spirit of truth and the spirit of error.
   
• Luke 4:35-36
  But Jesus rebuked him, saying, "Be quiet, and come out of him!" And when the demon had thrown him in their midst, it came out of him and did not hurt him. Then they were all amazed and spoke among themselves, saying, "What a word this is! For with authority and power He commands the unclean spirits, and they come out."
   
• Luke 8:32-33
  Now a herd of many swine was feeding there on the mountain. So they begged Him that He would permit them to enter them. And He permitted them. Then the demons went out of the man and entered the swine, and the herd ran violently down the steep place into the lake and drowned.

• Matthew 7:15-18
  "Beware of false prophets, who come to you in sheep's clothing, but inwardly they are ravenous wolves. You will know them by their fruits. Do men gather grapes from thornbushes or figs from thistles? Even so, every good tree bears good fruit, but a bad tree bears bad fruit. A good tree cannot bear bad fruit, nor can a bad tree bear good fruit.

Many will say to Me in that day, "Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?" And then I will declare to them, "I never knew you; depart from Me, you who practice lawlessness!"
