They may not know what the future holds, yet they recall the prophecies. As Zechariah proclaimed: "And it will be in that day, the Lord will destroy the names of idols from the earth, and they will no longer be mentioned... And I will burn out the unclean spirit from the earth" (Zechariah 13:2). From this, it becomes clear that the demons will not endure eternally, nor will their malevolence persist indefinitely. Out of fear of judgment, they exclaim, “You have come to destroy us” (Mark 1:24; Matthew 8:29). Yet, wishing to remain in the world and realizing that they will be punished for their actions, they beseech to be sent into the swine.
What sort of swine are these? Are they not akin to those spoken of, "Do not give holy things to dogs, and do not cast your pearls before swine, lest they trample them under their feet" (Matthew 7:6)? These represent individuals, much like unclean animals, stricken with a lack of reasoning, who tarnish the inherent beauty of the virtues bestowed upon them through their vile actions. They plunge into destruction, heedless of the prospect of retribution. As though they were careening down the steep incline of moral decay, they drown in the currents of this worldly existence, perishing as if suffocated for lack of air. The one who hesitates to engage in the tumultuous waters of pleasure cannot inhale the Spirit of life.
Thus, we observe that humans inflict torment upon themselves. If some people did not live like swine, the devil would never have dominion over them; or if he did, he would not obliterate them but merely test them. Perhaps, after the Lord’s coming, the adversary can no longer ensnare the righteous, narrowing his focus to those who are frivolous, much like a robber who preys upon the defenseless and torments the feeble, knowing the strong would disregard him and resent his actions.
However, someone may question: why does God permit this to happen at the hands of the devil? My response would be this: for the righteous to be tested and the wicked to be punished; such is the consequence of sin. Consider how the Lord may send illness, tremors, malevolent spirits, blindness, and various afflictions as recompense for the sins of the unrighteous. Yet, let us return to our primary discussion.
