Larry Wessels, director of Christian Answers of Austin, Texas/ Christian Debater (YouTube channel CANSWERSTV at websites: & presents a Biblical analysis & discussion of the subject of demon possession with fellow Dayspring Fellowship member ( David Harrell. David Harrell graduated from Austin Presbyterian Theological Seminary in 1976 & went on to pastor a Presbyterian church before becoming a member at Dayspring Fellowship in Austin, Texas during 1982 & later serving as an elder there.
During the 1980s David Harrell had two years of intensive interaction with a demon possessed church member exhibiting evidence of multiple demons. Larry Wessels, too, had experience with this same demon possessed person as mentioned in this video (which is also referenced in another video “DEMONIC POSSESSION CASE: DEALING WITH THE DEVIL – WHAT JESUS HAS DONE TO SATAN” at The Bible itself tells of demon possessed people being inside the church (or in this case the synagogue) Luke 4:33-36, “33 And in the synagogue there was a man, which had a spirit of an unclean devil, and cried out with a loud voice,
34 Saying, Let us alone; what have we to do with thee, thou Jesus of Nazareth? art thou come to destroy us? I know thee who thou art; the Holy One of God.
35 And Jesus rebuked him, saying, Hold thy peace, and come out of him. And when the devil had thrown him in the midst, he came out of him, and hurt him not.
36 And they were all amazed, and spake among themselves, saying, What a word is this! for with authority and power he commandeth the unclean spirits, and they come out.”
The Bible gives some examples of people possessed or influenced by demons. From these examples we can find some symptoms of demonic influence and gain insight as to how a demon possesses someone. Here are some of the biblical passages: Matthew 9:32-33; 12:22; 17:18; Mark 5:1-20; 7:26-30; Luke 4:33-36; Luke 22:3; Acts 16:16-18. In some of these passages, the demon possession causes physical ailments such as inability to speak, epileptic symptoms, blindness, etc. In other cases, it causes the individual to do evil, Judas being the main example. In Acts 16:16-18, the spirit apparently gives a slave girl some ability to know things beyond her own learning. The demon-possessed man of the Gadarenes, who was possessed by a multitude of demons (Legion), had superhuman strength and lived naked among the tombstones. King Saul, after rebelling against the LORD, was troubled by an evil spirit (1 Samuel 16:14-15; 18:10-11; 19:9-10) with the apparent effect of a depressed mood and an increased desire to kill David.
Thus, there is a wide variety of possible symptoms of demon possession, such as a physical impairment that cannot be attributed to an actual physiological problem, a personality change such as depression or aggression, supernatural strength, immodesty, antisocial behavior, and perhaps the ability to share information that one has no natural way of knowing. It is important to note that nearly all, if not all, of these characteristics may have other explanations, so it is important not to label every depressed person or epileptic individual as demon-possessed. On the other hand, Western cultures probably do not take satanic involvement in people’s lives seriously enough.
In addition to these physical or emotional distinctions, one can also look at spiritual attributes showing demonic influence. These may include a refusal to forgive (2 Corinthians 2:10-11) and the belief in and spread of false doctrine, especially concerning Jesus Christ and His atoning work (2 Corinthians 11:3-4, 13-15; 1 Timothy 4:1-5; 1 John 4:1-3).
Most theologians believe that a Christian cannot be possessed because he has the Holy Spirit abiding within (2 Corinthians 1:22; 5:5; 1 Corinthians 6:19), and the Spirit of God would not share residence with a demon.
From missionaries’ experiences, demon possession also seems to be related to the worship of heathen idols and the possession of occult materials. Scripture repeatedly relates idol worship to the actual worship of demons (Leviticus 17:7; Deuteronomy 32:17; Psalm 106:37; 1 Corinthians 10:20), so it should not be surprising that involvement with idolatry could lead to demon possession.
Based on the above scriptural passages and some of the experiences of missionaries, we can conclude that many people open their lives up to demon involvement through the embracing of some sin or through cultic involvement (either knowingly or unknowingly).
