When man rebelled against God, the passions rebelled against reason – and from this arose all the difficulties which we encounter in the practice of virtue. Thus we see that many who appreciate virtue refuse to practice it, just as sick men earnestly desire health, but refuse the unpalatable remedies which alone would restore it. As this repugnance is the principal barrier to virtue, which, when known, is always valued and loved, if we succeed in proving that there is little foundation for such repugnance we shall have accomplished a good work.
The principal cause of this illusion is that we only regard the obstacles to virtue, and do not consider the grace which God gives us to overcome these obstacles. The servant of Eliseus was frightened at the numbers who were coming armed against his master, until God, at the prayer of the prophet, opened his eyes and caused him to see that Eliseus was surrounded by a still greater number of defenders. A like fear leads men to reject virtue, when they know not the succors which God reserves for it.
