"Then Jesus said to him, "Put your sword back in it's place! For all who take hold of the sword will die by the sword." Matt 26:52
This is a great back door reference to the great kingdom principle, "Whatsoever a man Soweth that shall he also reap." Gal. 6:7. Sort of, what goes around comes around. But this one is more specific. Violence follows the violent nature. But I see it's applicable in every direction. Specifically, if you practice deception, you yourself will be deceived. This is why you see people who practice deception for political gain will begin to believe in there own lie, and will set the stage for other spirits of deception. Many religious people believe in their ability to perceive deception, all the while buying into deception hook, line and sinker. Inspite of your deception perception prowess the rule is, "if you practice deception you will believe deception." The Spirit of Truth is the greatest enemy to the spirit of deception. Spirit of Truth get some.
