“We must love God, but let it be in the work of our bodies, in the sweat of our brows. For very often many acts of love for God, of kindness, of good will, and other similar inclinations and interior practices of a tender heart, although good and very desirable, are yet very suspect when they do not lead to the practice of effective love.” (cf. 1 Corinthians 13)
