In his heart, he knows those of whom it was said that they were “light.” The righteous person is light, of whom the Lord said: “You are the light of the world” (Matthew 5.14). If such a person is in any place, darkness disappears because of his light. It is as if a lamp were placed in a dark place, so that darkness is dispersed and the place becomes luminous. The same thing happens with the presence of the righteous in any place they stay; light spread and darkness disappears.

Similarly, with the saints, because of their spiritual reverence, darkness can find no opportunity for itself in their presence. Sinners are embarrassed to be around them on account of their dignity and holiness. No one dares in their presence to act in a degrading way, or say a bad word, but rather he is ashamed of himself and his conduct. The people present feel that a spiritual atmosphere has prevailed in that place as a result of the presence of one of these righteous people. If there was a sinful talk before their entrance, it stops, and everyone is quiet and the darkness disappears when they enter. No one can sin in their presence.

Are you the same? Have you become light after your repentance? Have you become even a small candle, giving dim light but in any case dispersing darkness? If you have not become such a light, then be very cautious of darkness. Remember at all times the saying of the Lord: “Let your waist be girded and your lamps burning” (Luke 12.35).
