Let’s continue to be strenuous in pursuing virtue. Let’s not grow tired of seeking it, for our Lord has become a guide for us and for every person who has a desire for the virtues. And so that it might not be tedious for us, St. Paul became our example when he said, “I die daily” (see 1 Cor 15:31). Now, if we were to think each day that we had to die that day, we would never sin at all. This is the explanation of Paul’s saying. If in the morning we imagined that we would never last until evening, and if at evening we thought that we would never see morning, we would never sin.
–Saint Athanasius the Great (c. 296-373)
