I keep "getting" that someone(s) out there could maybe benefit from hearing this message, so I'll go ahead and address it. . . . My knowledge on the matter derives from analyzing personal experience combined with ongoing, in depth research I've done concerning the methods and means of the demonic realm and their attacks and manipulation of both unbelievers and believers. . . .The following is my educated opinion on the subject.
When demons heal. . . .
Like everything else the dark side does, it is a mockery and semblance of the Spirit's ways. Demons (usually disguised as spirits, "familiars", "spirit guides", "ascended masters" etc.,) do not heal as the Spirit can heal but they do this: They will first induce a malady . . . or cause an accident and injury . . . or bring about a disease . . . THEN they will take it back or reverse it. They can "heal" so-to-speak a problem or harm that they first of all instigated. And they are clever and patient . . . so that it may seem like they are healing a long term illness, for instance, that "happened" to someone early in life, but in fact, it was them all along. And, as an added insult, when they do "heal" and take bake the curse or affliction . . . there is always an even heavier price to be paid later. So, while someone "benefiting" from demonic healing may think themselves fortunate and may even be grateful (not realizing where the evil supernatural power is actually coming from) . . . and for a while it may appear that they (the victim) are indeed in better shape after the "healing" or demonic "blessing" . . . sooner or later, the devil comes to collect his dues and the price is always much greater and usually quite tragic compared to the purported benefit.
For instance, let's say the victim has been suffering asthma . . . for year (caused by demonic influence in the first place, unbeknownst to the victim) . . . and then goes to a "medium" or New Age type "healer"/"channeler" . . . who apparently "cures" the illness . . . later . . . that victim may lose a beloved pet or even child or spouse in some horrible accident or even violent attack. The dark side takes its due one way or the other. They are inveterate liars, deceivers and lust to inflict great misery and suffering on unwitting dupes. This happens this way a lot. . . .
The great books on "pathological" traits and types of people (such as the book "Puzzling People" show other ways this whole dance works. The Psychopath (who I believe is usually just a demonically possessed or, at least heavily demonically influenced individual) will covertly and with supernatural ability . . . cause "misfortune" and trouble to enter their victim's life, often over and over. But then they will come to the rescue with "love bombs" and/or financial or "networking" (business connection) fixes to the victim's ongoing "bad luck."
In other words, The Psychopath (or the demon) causes the illness, disease, misfortune, accident in the first place, then rides in as the savior to fix it. Because supernatural elements are involved the victim doesn't see it and wouldn't believe it if you told them this was what was actually happening, as it all appears to be just "happening" or part of "natural" events and processes . . . "sometimes sh*t just happens" . . . they would say, not wanting to believe the elements of the demonic and ongoing invisible war between man, Satan and God. . . .
The vast majority, if not all of the New Age type "healers", "mediums", "spirit channelers", "spirit guides" etc., where they are operating outside of Biblical doctrine and teachings . . . are part of this dark charade. . . . Unfortunately, there are quite a few so-called "healers" who claim to be "Christian" who also are using these demonic means of "healing" (through first harming).
Now, the first antidote and answer to not being caught up in this type of insidious snare . . . is to start being aware that it is there. The demonic like to operate in the dark--they need to operate in the dark. So just becoming aware that this phenomena and method of the dark is really happening helps one straightaway to avoid becoming a victim to it. . . . And there are other helps as well . . . hopefully I can get to, if any is interested.... God willing . . .
And God bless
