Blessed are the pure in heart for they shall see God (Mt 5:8)
The image of God is reflected in a pure soul, like the sun in the water. A pure soul is the admiration of the Three Persons of the Holy Trinity. The Father contemplates His work: There is My creature! . . . The Son, the price of His Blood: the beauty of an object is shown by the price it has cost. . . The Holy Spirit dwells in it as in a temple . . . We cannot comprehend the power that a pure soul has over the good God. It is not he who does the will of God; it is God who does his will (Saint John Vianney).
