EXPERIENCE SPEAKS OUT
Grayson Ensign, a former Bible College professor and missionary to Jamaica made this statement:
" We have empirical evidence that Christians have been invaded by evil spirits, for we have extensive notes on the more than one hundred and fifty with whom we have worked in securing deliverance by the Lord Jesus Christ….Our testimony is grounded in literally hundreds of hours of deliverance work where we have experienced the most wonderful liberation of Christians from the control of evil spirits. We have been reared in a tradition that taught demons could not invade or control people and certainly not Christians. We tested every conceivable theory of explanation for what was happening. The only explanation that was systematically consistent and in harmony with the Word of God was that our brothers and sisters had been invaded by evil spirits" (1).
Kurt Koch, famous author of "Occult Bondage & Deliverance" and "Christian Counselling And Occultism" as well as many other books on cults and the occult, says the subject of Christian demonism is "hotly disputed" amongst Christians. He is right. However, he says that in his experience (which I am sure is enormous) only those who have no experience of deliverance stick to the "no-invasion" theory. Koch then gives a list of many noted ministers, doctors, professors and psychiatrists who DO believe it is possible for Christians to be demonised, because they have seen it.
He also says:
"I met a missionary in Africa who had actually been possessed himself for a period of eighteen months. He, like many others, had previously believed it was impossible for Christians to be possessed. However, his own experience made him change his theological outlook." (2)
Another person who found out that demons could indeed use Christians is Jessie Penn-Lewis, who experienced the Welsh Revival, and saw the excesses and satanic counterfeits that arose because of it. Her book "War On The Saints" is a much-valued work today because it has many modern parallels. Penn-Lewis writes of a case known to her:
In the Spring of this year (1912) [a certain Christian] who was possessed came here, and the spirits possessing her spoke through her in voices utterly unlike her own. They would utter through her the most awful blasphemies against God, and against our Lord Jesus Christ, and would prophesy concerning the Church…
(later)…Much prayer has been made for her, and with her. When the frenzy comes upon her, she is fearfully shaken, dashes about the room, is made to howl like a dog, her hands clenched, her face drawn with horrible contortions, etc. But the marvel to every one is that, although the frenzy is upon her every day, and sometimes once, twice or more in one day, her health is perfect, she sleeps well, and in the interval is THE MOST LOVELY-SPIRITED CHRISTIAN WOMAN."
This sister is not one who has not got faith. She is well grounded in the same faith, and has the same light as we have; but we have here to do with a demon, the like of which I have never met before, nor read about…" (3)
The woman in question was delivered, but not before much prayer and warfare against the demon had been accomplished. It was a lengthy process over a number of weeks, in which the demon was first muted, then silenced, and finally driven out by the authority of the name of Jesus, accompanied by howling and vomiting. The woman, freed from all effects of this horrible experience, was able to return to her missionary work.
Does this not show that popular theories should be tested in the light of the evidence, both biblical and factual?
