I do think the Lord Jesus cast demons out of unbelievers, though I think some did become believers as a result. We have so many accounts of His healing and casting demons out of masses of people. Some of these were Jews, but unregenerated (I think) and others Gentiles (in both groups some of whom afterwards became believers).
What Mary says is true though, that if – per Matt 12:43 ff – someone has a devil expelled and is not converted to Christ, the devil can return and bring seven worse devils with him (although He was talking of the case of unregenerate, unrepentant Israel in this saying).
Is there no purpose for possession in these days? Is there any purpose for any evil? We know there must be, for it exists. Hell has
its purposes as well as Heaven. Of course the sovereign Lord overrides all evil and works it to His good ends. If one were to go to primitive lands (in Asia, Africa, South America, etc) one might see things unheard-of here in the West; I refer to places where the Gospel of Christ and the power of God is not known, or is rejected. Has the human condition undergone massive change (immunity from demonic attack) because Christ came into the world? In 2 Tim 2:26 Paul says that some are caught in “the snare of the devil, who are taken captive by him at his will.”
Now, I often hear it said that Christians are immune from possession of the devil, and I fully agree, with this caveat: there is a difference between full possession, where a person’s volition and hence their actions are taken over by an evil spirit, their personalities “submerged” in the evil spirit’s takeover, and the lesser varieties of influence and infiltration by devils.
Consider what Calvin says in his comments on Eph 4:27, "Neither give place to the devil"?
Neither give place (τῷ διαβόλῳ) to the devil. I am aware of the interpretation which some give of this passage. Erasmus, who translates it, “neither give place to the Slanderer,” (calumniatori) shews plainly that he understood it as referring to malicious men. But I have no doubt, Paul’s intention was, to guard us against allowing Satan to take possession of our minds, and, by keeping in his hands this citadel, to do whatever he pleases. We feel every day how impossible, or, at least, how difficult it is to cure long-continued hatred. What is the cause of this, but that, instead of resisting the devil, we yield up to him the possession of our heart? Before the poison of hatred has found its way into the heart, anger must be thoroughly dislodged. [Taken from this post:

To give you a more current example with respect to a believer: Take someone who has been genuinely converted to Christ, but has backslidden and reverted to taking drugs – the psychedelic,
pharmakeia variety – and has opened him or herself to demonic influence deep in their being. Now, that one who belongs to Christ, and has been indwelt and sealed (unto eternal salvation – Eph 1:13-14) by the Spirit of God – is His beloved possession – cannot be possessed by another, for who can overpower the Almighty or take what is His? But there is such a thing as spiritual fornication – adultery – whether it be deliberate or through deception, and one might expect God to act in reclaiming one of His children from such; how He acts will depend of the circumstances of the situation. He will not lose a one of those who are His!
But do not be deceived: sin will give entrance to the spirit of ungodliness. How? Well, take sins of the flesh, sexual lust, gluttony, sloth, habit-forming drugs, alcoholism . . . continual indulgence weakens the volition in man, leading to passivity of the will and the giving of oneself over to strong desires of various sorts – do you think that such passions cannot be amplified by the demonic, that giving place to the devil’s temptations will not also give opening to his activity, the end of which is the enslavement of the whole person?
Then we have the modern “arts” – the
arts of Babylon I call them – wherein we are addicted to entertainment, fantasies that we utterly delight in . . . I refer, of course, to the movies and television. For some, they turn over the exploits of Batman or – you name your favorite superheroes – in their minds far more than the exploits of the Champion of Heaven and His singlehanded warfare against the entire demonic realm, and the stunning way He became the “Death of death” that we might no longer taste its horrible bitterness.
Who is the brilliance, the genius, behind the Babylonian arts that so enthrall us? When we give our imaginations to the panoply of demi-gods – contemplating their powers, might, victories, adversaries, defeats, triumphs, etc – what are we doing? There are some who give themselves over to this to such an extent that their spiritual lives are perfunctory – functionally negligible – exercises, while the real action in their hearts are the high-tech wonders that have captivated their souls. Is there demonic activity in such?
Please note: I make no law whatsoever with regard to movies, TV, books, comics, graphic novels, computer games, etc. I have the freedom to watch or read what I will, and I would take it from no one. But I guard my mind against the entrance of that which is filthy, or which would ensnare me in its power, that which would take up too much of my time. Spiritual awareness is of the highest importance to me. Awareness of what? The King of course! Without an ongoing – constant – communion with Jesus I am a broken and weak wretch. He is that which preserves me from temptation, that which upholds me in trials.
We must learn this, each of us who name His name, for the days are coming when we shall need this cultivated practice of drawing on His presence for every need – in times of peace, and times of trouble.
We are so smug about our supposed “perpetual deliverance” from the demonic that we grow lazy and careless. We give our attention all else but that which is the one crucial thing – it is in the intimate presence of our Savior that we are safe from all that will come to us. And the preaching of the Gospel, be it on the streets, in the pulpit, or individual witness, is the power of God and the weapon of the church.
Sorry to come on so heavy, but I see trouble coming quickly, and we unaware and unprepared.
