This doctrine of holy Scripture, as you know, is to be found in the very nucleus of the spirit of Opus Dei. It leads you to do your work perfectly, to love God and mankind by putting love in the little things of everyday life, and discovering that divine something which is hidden in small details. The lines of a Castilian poet are especially appropriate here: ‘Write slowly and with a careful hand, for doing things well is more important than doing them’ .
I assure you, my sons and daughters, that when a Christian carries out with love the most insignificant everyday action, that action overflows with the transcendence of God. That is why I have told you repeatedly, and hammered away once and again on the idea that the Christian vocation consists of making heroic verse out of the prose of each day. Heaven and earth seem to merge, my sons and daughters, on the horizon. But where they really meet is in your hearts, when you sanctify your everyday lives. (Conversations, 116)
