God did not create us to build a lasting city here on earth [1], because 'this world is the way to that other, a dwelling place free from care' [2]. Nevertheless, we children of God ought not to remain aloof from earthly endeavors, for God has placed us here to sanctify them and make them fruitful with our blessed faith, which alone is capable of bringing true peace and joy to all men wherever they may be. Since 1928 I have constantly preached that we urgently need to christianize society. We must imbue all levels of mankind with a supernatural outlook, and each of us must strive to raise his daily duties, his job or profession, to the order of supernatural grace. In this way all human occupations will be lit up by a new hope that transcends time and the inherent transience of earthly realities. (Friends of God, 210)
