Consider the reason for Peter's exaltation and blessings. It was because he declared, “You are the Christ, the Son of the Living God.” However, it was not merely the words he spoke that brought him blessing, but the condition of his heart. Would you like to understand that Peter's joy was not derived from uttering those words? The demons voiced similar statements: “We know who you are; you are the Son of God.” Peter acknowledged the Son of God, and so did the demons; what then distinguishes them, O Lord? The response is clear: Peter proclaimed his faith out of love, while the demons expressed their acknowledgment out of fear. You may ask, “Do demons not believe and tremble?” The answer is this: “I tell you, I make a distinction: faith must be active through love.”
From this perspective, it becomes evident that while the demons possessed knowledge, they lacked love. They were consumed by their fear of punishment from Him, whose justice was devoid of love. He disclosed Himself to them only to the extent deemed necessary, not in the same manner as He did to the holy angels, who fully participate in the eternal essence of the Word of God. Rather, He revealed Himself as one to be feared, as He liberates all whom He calls into His kingdom and eternal glory—a truth that is eternally valid and genuinely everlasting. Thus, He did not unveil Himself to the demons as the source of eternal life and unending light that enlightens the righteous, whose hearts are purified through faith by witnessing that illuminating truth. Instead, He demonstrated His authority through transient manifestations of His might, utilizing hidden signs more readily perceived by angels, even those who are evil spirits, than by frail humanity.
A quiet faith serves little purpose if it is devoid of love. The demons expressed belief in Christ, but without love; they said, “What have you to do with us?” Their acknowledgment was real, yet love was absent, for they were demons. Therefore, do not take pride in your faith, lest you become akin to demons.
