The love of God is acquired by resolving to labor and suffer for Him, and to abstain from all that displeases Him, and by carrying this resolution into practice as occasion arises. But to be able to do it well in great things, it is necessary to attend to it in small. -St. Teresa
St. Vincent de Paul was remarkable for this virtue. Because he would not consent to anything in the least contrary to justice, simplicity, and charity, he was obliged to bear many unfavorable remarks, indiscreet questions, reproofs, affronts, importunities, and other unpleasant treatment from members of his own Order, as well as from others. In such cases, he was never observed to give a sign of impatience, or to utter a word of complaint, but rather, in order to show the strength of his love for God, he spoke and acted with more than his usual sweetness and tranquillity.
Whoever has not experienced it, will not be able to believe how much we gain by being careful not to fail in little things; for the devil, by means of these, makes gaps and breaches through which great things can enter. -St. Teresa
