Remember, Monsieur, that Saint Augustine says that a person who does not obey the doctors is doing his best to kill himself.

[A] truly humble spirit humbles itself as much amid honors as amid insults, acting like the honeybee which makes its honey equally as well from the dew that falls on the wormwood as from that which falls on the rose.

God has great plans for you, directed towards helping you do what Jesus Christ did when He was on earth. This requires you do resist temptation vigorously, with special confidence in the assistance of His Divine Goodness. Courage then, Monsieur. Be faithful to Him, and the Divine Goodness will be favorable to you.

A doctor who keeps a person from becoming ill deserves more merit than one who cures him.

[I]n order to raise a soul to the highest perfection, He allows it to pass through dryness, brambles, and combats, causing it thereby to honor the times of weariness in the life of His Son, Our Lord, who suffered various kinds of anguish and abandonment.

Since I am a great sinner, I cannot reject those who have been, provided they have good will.

You should not open your mouth except to express gratitude for benefits you have received, and never to mention your discontent.
