On no account, beloved, must you flee from what may be a chance for acquiring virtue. On the contrary, whenever such a chance offers itself, you should accept it with joy, regarding as best and most welcome such things as are unpleasant to your heart and evoke no sympathy in you …. [Y]ou should realize that the opportunities for virtue you meet with are the best means you can have for acquiring it, given you by God in answer to your prayer. Having formed a desire to gain virtue, you have, of course, prayed God to grant it to you; and in praying for it, you could not avoid praying also for the methods and means of acquiring this gift. But God does not give, for instance, the virtue of patience without afflictions, nor the virtue of humility without humbling occasions of degradation and dishonor. So, after your prayer about these virtues, He sends you corresponding opportunities. What are you doing, then, in running away and avoiding them? ..
So decide to welcome gladly the chances you meet for virtue, and the more gladly, the more difficulties they offer. For in such cases our virtuous actions evoke great courage and reveal great moral strength; and through this we make each time a considerable step forward on the path of virtue, which alone should be our constant aim.
