Let none think that Satan retreats from his prey without resolve to return. He is tireless in his malice and relentless in his schemes. The evil spirit, finding no rest, returns to the soul it once occupied, and finding it empty—brings with him a company more wicked than himself. Thus the last state becomes worse than the first. Here Christ shows us the desperate folly of resting in temporary deliverance without seeking lasting union with himself. It is not enough to expel sin; it must be replaced with righteousness. It is not enough to cast out the devil; the Spirit of Christ must dwell within.
