Satan may or may not be the cause of difficult situations, where all seems hopeless and we're going through great difficulty, but even if he is not, he is prowling around to take advantage of it in the hopes that he might pick us off. What does the roaring lion most likely attack? The strays, the ones on the fringes, and those not keeping up with the flock. Spiritually, the ones most likely to be attacked are those who are not spiritually with it. Wearied by a barrage of problems, they begin to separate themselves, then Satan, the roaring lion, picks them off.
He is especially adept at taking advantage of people's feelings. All too often, we are dominated by our emotions rather than facts or, we could say, the truth of God. In such a circumstance, it is easy for us to get our feelings hurt, ignore the facts, and proceed to lie to ourselves, just as Satan did to himself when he first sinned.
