Faith is our response to we cannot comprehend of God, to the mysteries God. The more God draws us in, the more He reveals of Himself, the more mysterious He becomes, through these mysteries the roots that nurture our faith grow deeper, spread more broadly, and drawn in more of the waters of life. These mysteries are elements of our faith, the “assurance of things hoped for, the conviction of things not seen” (Hebrews 11:1).
Faith is an act of the human will and intellect that is only possible through the grace of grace of God and the cooperation of the Holy Spirit. According to St. Thomas Aquinas, “Believing is an act of the intellect assenting to the divine truth by command of the will moved by God through grace.”
