They are simply dangerous foes. They send you into drugs or some other sin.
When the Bible exhorts to “take captive” every thought, these are intended to be arrested and hauled off to jail. It’s a telling image, but how?
How many a saint has dabbled with sin simply out of boredom? How many a saint has sought a release from stress? How many a Christian has reacted against frustration by throwing himself into sin?
Because of boredom, David falls with Bathsheba. Because of stress, Elijah abandons post and runs off to the desert. Because of frustration, Moses calls it quits and retires to shepherding.
If you are in Christianity for the long haul, you will eventually grapple with these three, which threaten to become your demise.
This is why the fruits of the spirit counter each. Instead of boredom, we have joy. For stress, peace. In place of frustration, trust. In Christ, we possess the arms to counter the devil’s wiles. This is not to say I have perfectly mastered it. No, I rather encourage myself while encouraging others.
