For the Christian, the knowledge of God is not an endless course of reasoning as to His essence and perfections, such as that of a mathematician concerned with the properties of a triangle or circle. There have been many philosophers and even theologians who held fine and noble ideas of God, but were none the more virtuous or holy as a result of it. The knowledge we must have is what God Himself has revealed concerning the Blessed Trinity; the work of each of the Persons in creating, redeeming and sanctifying us. The knowledge we must have is what God Himself has revealed concerning the Blessed Trinity; the work of each of the Persons in creating, redeeming and sanctifying us. We must know the scope of His power, His providence, His holiness, His justice and His love. We must know the extent and multitude of His mercies, the marvelous economy of His grace, the magnificence of His promises and rewards, the terror of His warnings and the rigour of His chastisements; the worship He requires, the precepts He imposes, the virtues He makes known as our duty, and the motives by which He incites us to their practice. In a word, we must know what He is to us, and what He wills that we should be to Him.
