The intellect, the conscience, the loving power of the soul- must initially be offered to God as a holy sacrifice. The firstfruits and the highest of our true thoughts must be continually devoted to remembrance of Him, engrossed in His love and in unutterable and boundless longing for Him. In this way we can grow and move forward day by day, assisted by divine grace. For by always cleaving to God in this way our intellect will become one spirit with the Lord, as St Paul puts it.
