Well, not everyone who professes to be a Christian is. In fact, most “Christians” are nominal at best. Now, they may not know this. Most of them don’t. So, I don’t use the term “Christian” the way the world uses it, or the way that you apparently use it, for that matter. I’m talking full-throated, Bible believing, Holy Spirit filled people. The vast majority of “Christian” denominations either don’t believe what the Bible says or have distorted the meaning(s) of what it says. And they blaspheme and deny the power of the Holy Spirit. They can call themselves “Christians” all they want, but it doesn’t make it so. I can paint spots on my cat and call it a leopard, too. So what? All it means is that I’m deluded into believing a house cat is a wild beast. So I don’t count those “Christians” in my tally to begin with…whereas it sounds like you do. The people I’m talking about are men of God who I trust and who I know in my spirit are the real deal. These people have rebuked these crafts and they left. On the topic of demon possession/oppression as it pertains to Christians in particular, you are partly correct and partly incorrect. Humans are made of three parts: spirit, soul/mind, and physical body. A truly saved person is occupied by the Holy Spirit. This happens at the moment of salvation. So, a demon cannot “possess” the spirit of a Christian. The struggle from the moment of salvation until death is sanctification of the body and soul/mind. It is an ongoing process that does not end until death. The body and soul are the battlegrounds where satan attacks, with a primary emphasis on the soul/mind. Even a truly saved person can still have parts of their soul/mind that are under the influence (or even control to some degree) of the other side. The process of sanctification is actually the process of getting back and retaining control of those areas. The Bible talks of “renewing your mind with the washing of the word”. This is precisely what it’s talking about. My spirit is saved, but I need to get my soul/mind up to pace with it in order to live an effective Christian life and be able to manifest the power of the Holy Spirit the way that Jesus and the apostles did. This is the reason that some Christians are able to manifest things like healing and some aren’t. Those that are more mature Christians and have worked to get their minds in agreement with their spirits, and thus are able to operate the way that all Christians are intended to operate. All that to say, when a Christian’s mind/soul is not “renewed” and constantly progressing, it is much easier for demonic influence to take hold. And yes, this happens all the time. Also, demons can’t do these sorts of things to Christians without their consent/cooperation. At some point, they have agreed to cooperation with evil spirits to dominate parts of their personalities. This contract can be revoked, but only if the person wants it revoked..and that’s only an option if they are even educated enough to realize that there is such a contract in effect to begin with. And guess what, many (I’d even say most) Christians don’t have that awareness. Hell, many of them don’t even really believe demons are real in the first place. And then some actually like their demons. This is the case with addictions. Well, a demon doesn’t have to leave if you want it there. Now, the difference between a Christian suffering from demonic oppression and a non-Christian suffering from the same is that the Christian actually has options. If the Christian can come to the realization of the authority given to them by Christ, renounce any agreements they’ve made that allowed the demons access (break the contract), and then demand the demon to leave, it has no choice but to leave. But it’s not over. They also have to maintain their deliverance from demons, or else they will come right back, often with greater force. To maintain it, the person must take ownership and keep their mind in step with their spirit. It’s not necessarily easy, either. In a lot of ways it’s like learning to walk or ride a bike for the first time. You’re going to fall and get scrapes. But you keep getting up and doing it until you’ get it right. I’ve had many experiences with this stuff personally, so you can believe me or not, but I’m telling you it’s is real. For example, myself and my wife have had to deal with generational curses/oppression and breaking those off from us, on both sides of the family. My first marriage was full of demonic problems. Since I have taken ownership, learned about my authority over this stuff, worked hard at my part of my own sanctification, and then exercised that authority, I have freed myself from this crap. It has been a long road and I still have to fight to maintain it all, but it’s gotten easier. My father, however, is struggling. Myself and some family cast some demonic entities off of him a few years back without telling him about it. We also didn’t tell my mother we did it. She called the next day and told me “something’s up with your dad, it’s like he’s a different person.” She knew nothing about what we had done. If I had any doubts before, they were removed with that phone call. Now, because my dad has refused to break those agreements and own his deliverance, he still has these problems. They came back, in other words. So, we can deliver him, but we can’t stop him from “liking” or “being comfortable” with having those demons in his life. Unless/until he decides to own his deliverance, he will continue to have those issues. In any case, the good news is that at some point, you and I will both know whether or not I’m correct about these”aliens”. As you watch all of this this unfold, just keep evaluating it the way that you would anyway (with an open mind and with discernment). Just keep what I’m telling you in the back of your mind as a possible explanation for it. And I’d say, learn more about there biblical story and the plan of God vs that of satan. I’m quite confident that the more you learn about it, you’ll see it as an increasingly stronger explanation for all of this stuff.
