If we would therefore behave like good soldiers of Jesus Christ, we must be always on our guard, and never pretend to lay down our spiritual weapons of prayer and watching, till our warfare is ended by death; for if we do, our spiritual foe will quickly prevail against us. What if he has left us? It is only for a season; yet in a little while, and, like a roaring lion, with double fury, he will break out upon us again. Satan is such a evil enemy, that he seldom leaves us after the first attack. As he followed our blessed Lord with one temptation after another, so will he treat the Lord's servants. And the reason why he sometimes does not renew his attacks, is because God knows our weaknesses and at times are unable to bear an attack. Sometimes the pause in the temptations come because our adversary thinks it is better to assault us at a more convenient season.
