We ought not to think that [the Devil’s] activity is primarily, or even mainly, to be seen in dramatic, extraordinary “power” encounters, where people are exorcised or delivered of demons. His warfare against us – and make no mistake it is real – takes place primarily at a far more frightening level: at the level of ordinary, everyday life.

We see this illustrated repeatedly in the Epistles when our battle with the Devil is mentioned. We keep him at bay when we deal promptly with anger and do not allow it to fracture relationships. (Eph 4:28) We elude his ravenous jaws when we bear up under suffering, and cast our cares on God. (1 Pet 5:6-11) We resist his advances and cause him to flee, when we stop compromising ourselves with the world, and commit ourselves wholeheartedly to God. (Jas 4:4-8)
