Once while I was recollected in this company I always bear with me in my soul, God seemed so present to me that I thought of St. Peter’s words: You are Christ, Son of the living God (Mt 16:16). For God was thus living in my soul. This presence is not like other visions, because it is accompanied by such living faith that one cannot doubt that the Trinity is in our souls by presence, power, and essence. It is an extremely beneficial thing to understand this truth.
