Question: Can a Demons indwell a Christian?
Answer: No, Demons cannot indwell a Christian.
"When the unclean spirit is gone out of a man, he walketh through dry places, seeking rest, and findeth none. (43)
Then he saith, I will return into my house from whence I came out; and when he is come, he findeth it empty, swept, and garnished. (44)
Then goeth he, and taketh with himself seven other spirits more wicked than himself, and they enter in and dwell there: and the last state of that man is worse than the first. Even so shall it be also unto this wicked generation." - Matthew 12:43-45
The above verses in Matthew 12:43-45 are an account of a demon-possessed person. The demon leaves the lost person, who probably was a very evil man. The man is lost; and, in the demon's mind, he will remain in his evil condition until he enters Hell at death. Therefore, he exits the person and prowls around looking for other victims he can deceive into Hell. Whatever area the demon was canvassing was "dry," no water. This figure of speech was illustrating that there were no good candidates for him to indwell. (v. 43).
The "rest" he was seeking was not that of inactivity; but, the rest and peace he would have in keeping people away from Jesus Christ, whom he hated. One must remember that on the Original Creation these demons had followed their god, Satan, and now have the death sentence of eternal damnation in the Lake of Fire.
"Then shall he say also unto them on the left hand, Depart from me, ye cursed, into everlasting fire, prepared for the devil and his angels:" - Matthew 25:41
After some time had passed, the demon decides to return and check out the person he had abandoned (v.44). He found that this person had completely changed his life from the evil person he had been. Three things were observed by the demon and are as follows:
1. The man was empty - he was unoccupied, with no Holy Spirit, and still lost.
2. He was found swept clean. He had made a complete change. He was now kind, polite, helpful to others; he would neither "swear, drink, or chew; or date nasty girls that do."
3. He appeared garnished. (Greek, "decorate, trim") He had dressed himself up, and modeled what a Christian should be. He loved the attention he was receiving from others, as his pride swelled like a balloon!
In God's eyes, he was just another lost person, gloating in his self-righteousness, just like the Pharisees who hated Christ.
"And the Pharisees also, who were covetous, heard all these things: and they derided him. (14) And he said unto them, Ye are they which justify yourselves before men; but God knoweth your hearts: for that which is highly esteemed among men is abomination in the sight of God."- Luke 16:14-15
After seeing the change in this man, from completely evil to completely good, the demon was completely shocked, as he would never have suspected this would happen. Demons are not illiterate; but, very intelligent. Demons are at rest when they are actively serving their father, Satan, in keeping anyone they can from trusting Jesus Christ as payment for their sins by His death and Resurrection; thus inheriting eternal life as a free gift.
Seeing the change of this man from evil to a model citizen was totally unnerving to the demon. He also was not going to take a chance that this man could also, in the future, with a Christian's influence, exchange his self-righteousness for the righteousness of Jesus Christ.
"Therefore if any man be in Christ, he is a new creature: old things are passed away; behold, all things are become new." 2 Corinthians 5:17
The demon leaves and secures seven demons, more wicked than himself, and explains the situation to them. They could not risk losing one of Satan's children to Jesus Christ; so, they all decide to indwell the man to make sure he never believes the truth.
"Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me." - John 14:6
The demons will do everything within their power to keep him away from being witnessed to by a Christian. They will keep his mind saturated with how good he is, how many friends he has, how many people respect him; until he enters Hell after his last heart beat. The demons shout for joy as they hear another one of their deceived victims screaming from Hell, just as the Rich Man did in Luke 16:19-30.
"And in Hell he lifted up his eyes, being in torments, and pleaded for just a drop of water to wet his tongue, as he was tormented in this flame. He begged for someone to tell his five brothers about Jesus Christ, so they would not come to this place of torment." (Paraphrased)
No Christian can be indwelt by a demon, or demons. Your body is a temple of the Holy Spirit.
" What? know ye not that your body is the temple of the Holy Ghost which is in you, which ye have of God, and ye are not your own? (19) For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God's." 1 Corinthians 6:19-20
Christians are sealed by the Holy Spirit.
In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise, Ephesians 1:13
The Holy Spirit is greater than any demon.
Ye are of God, little children, and have overcome them: because greater is he that is in you, than he that is in the world. 1 John 4:4
Demons can influence a Christian and put thoughts into your mind; as well as use lost people to attempt to control your life in opposition to God's will. Choose your friends wisely!
"Now I beseech you, brethren, mark them which cause divisions and offences contrary to the doctrine which ye have learned; and avoid them. (17) For they that are such serve not our Lord Jesus Christ, but their own belly; and by good words and fair speeches deceive the hearts of the simple." - Romans 16:17-18
