It sounds more like the stuff of Stargate and Dr. Who than the Bible, but portals (gateways between the spiritual and the physical realm) are very real.
Scripture does not explain how it all works. We can affirm the reality of demonic (and angelic) activity, though we have no clear descriptions of their deployment. It seems, however, that certain activities may open our minds and souls to the spiritual realm in dangerous ways.
These “gateways” are doors that we open, perhaps quite unsuspectingly. But we should not underestimate the power of the demonic forces t0 exploit such openings.
Years ago, Paul Hiebert described what he called “the excluded middle.” Simply stated, Hiebert observed that the Western world rarely makes direct links between the physical and the spiritual world. We have excluded the middle zone where the physical realm and the spiritual realm have tremendous interplay; just ask witchdoctors and voodoo priests. But our blindness to Satan’s schemes does not annul them. If anything, it makes us far more spiritually vulnerable.
What might be some of the gateways?
Drugs and alcohol—anything that alters our mind or consciousness—anything that hands control of our will to forces other than ourselves—clearly form a gateway. Many people testify to the spiritual darkness and bondage that their addictions have spawned.
It’s likely that that some music and movies serve as such gateways. It’s not just a matter of desensitization but of demonic infiltration. Gratuitous violence and explicit sexuality open our souls to new levels of darkness.
Pornography—the degradation and objectification of that which God intended to be pure and holy—is surely one of the largest spiritual gateways in our culture.
We dismiss these things as “the new norm” or excuse them as “recreation” or “entertainment.” But I wonder if we had the spiritual eyes of Elisha’s servant (2 Kings 6:17) if we wouldn’t be terrified by the swirling wicked hordes around us, to which we remain mostly oblivious.
It’s insidious and treacherous—far more than our “sinful nature” at work. It’s the powers of darkness and spiritual forces of wickedness (Ephesians 6:12) that seek first a foothold and then our souls.
Let’s shut the gates.
