I think someone has watched one too many fantasy horror movies. This reads like a synopsis for a bad Hollywood movie written by someone who only knows stereotypes about the Bible.
Actually it takes the bible quite seriously.
Maybe it isn’t the very self same demon, but they’re all slaves of Satan.
People too often want to find a recipe for a nice life in the bible. That’s actually a kind of soft hell, rather than a portion in heaven. The bible says the kingdom of heaven advances forcefully (or violently) and forceful (or violent) men lay hold of it. The violence in this context is by the divine forces of good against the satanic forces of evil.
And you know what? Fantasy horror movies hint at a side of reality that many of us have hidden from in the soft hell of a nice life.
Ironically enough, outright wickedness and squalor is easier to deal with than the soft illusions of normalcy. The normal won’t want God very much.
But in the face of the bad news, we shouldn’t forget that we have stunning good news to claim — the gospel of our Lord Jesus Christ. “Believe on the Lord Jesus Christ and you shall be saved — you and your household.” The more the merrier, literally.
Don’t pay TOO much attention when Satan says “Look at me.” Because he knows what God is doing and is reduced to trying to be a distraction until God has accomplished it. There is a kind of balance to be observed. We clean up trash, but we don’t spend our whole lives obsessing about trash. That would be to miss the point of what we do when the trash has been cleaned up.
