The devil is like a roaring lion, seeking whom he may devour. This roaring lion is no different than the fisherman who tries to catch fish he may devour. Like a fisherman, the devil knows we are not going to come running to him if he just beckons to us. So he needs to outsmart us by attempting to lure us away from the peace of God's lake and into his grasp. His means to accomplish this is a little bait called temptation.
Temptation is a funny thing.
One issue that everyone has in common is that each of us is tempted at one time or another. But every man is tempted when he is drawn away of his own lust and enticed. Satan is a smart fisherman because he knows that it would be foolish to tempt sinners. Like any good fisherman, you don't fish for the fish you have already caught and have in the tank. He mostly casts his lures at those living for God.
