Questions like these intrigue me. Although the answer is “no”, it doesn’t focus enough on the qualifying statement that one must be Christian to be immune.
“Every kingdom divided against itself is laid waste, and a divided household falls. And if Satan also is divided against himself, how will his kingdom stand? For you say that I cast out demons by Beelzebul. And if I cast out demons by Beelzebul, by whom do your sons cast them out? Therefore, they will be your judges. But if it is by the finger of God that I cast out demons, then the kingdom of God has come upon you. When a strong man, fully armed, guards his own palace, his goods are safe; but when one stronger than he attacks him and overcomes him, he takes away his armor in which he trusted and divides his spoil. Whoever is not with me is against me, and whoever does not gather with me scatters.
“When the unclean spirit has gone out of a person, it passes through waterless places seeking rest, and finding none it says, ‘I will return to my house from which I came.’ And when it comes, it finds the house swept and put in order. Then it goes and brings seven other spirits more evil than itself, and they enter and dwell there. And the last state of that person is worse than the first.”
Basically, when the unclean spirit was cast out, the person they inhabited never decided to sell their house to God. They left the “For Sale” sign up, and the demon already knew it was great real estate before. But what does it mean to sell the property to God? Just like a Real Estate transaction, when you sell the property to God, you’re signing a contract that is completely drawn up in the Bible. If you violate the contract, God makes decisions on what to do next.
In Saul’s case, God sent an evil spirit to plague him. From the descriptions, it’s more than simply an annoyance like what we see with Satan tempting Christ in the desert, and more direct than what happened to Job.
Saul believed that God existed, even had encounters that directly proved this because of Samuel’s guidance. Belief simply wasn’t enough to make him immune to the affliction.
You might be thinking “Well duh, Alethea, a Christian is someone that follows Christ- not someone just believes that God and Christ are real”. I get that, but that is not how we treat it. The Christian community has a problem with accepting that someone has converted to Christianity simply because they said a Prayer of Acceptance with them. Look at all the revivals you or others have attended, watched on YouTube or heard of from missionaries. The Christian Community has watered down what it means to be Christian because we measure a revival’s success by the number of people that show up to pray the Prayer of Acceptance.
I can’t count how many people I’ve heard say that the Prayer of Acceptance is all you need, and from that point forward you are always saved. If you don’t end up changing your ways, then you weren’t sincere and the Holy Spirit never entered your life which is why you’re experiencing turmoil, etc, etc. All of these are excuses to try and make “Once Saved, Always Saved” a truth. It also leaves the door open for wanton sinning in the hands of someone who doesn’t have the strength to prevent a relapse.
So let’s go back to the question, and reframe the answer: Can a Christian be possessed by a Demon?
Only so long as you’re holding up your side of the contract are you immune.
