"Now, have you ever considered, that God lays such stress upon the keeping of His commandments, and that He promises such great benefits in return for their faithful observance?  You will then agree with me, that our whole happiness consists in keeping faithfully the commandments."

"If you wish, dear brethren, to experience the magnitude of the goodness of God, then make it your duty to observe exactly what the commandments order you, and you will see with amazement how God cares for those who strive to please Him. If you wish to see a proof of this, turn to the pages of Holy Scripture, and there you will find full confirmation of this...the prophet Elias hid himself in the woods in order to escape the persecutions of Queen Jezabel.  There, deprived of all human aid, do you think that the Lord allowed him to die of hunger?  No, dear friends, certainly not.  The Lord did not lose sight of His faithful servant.  He sent at once an angel from heaven, to console him, and to bring him everything that was necessary for his maintenance."

St. John Vianney, Sermon-The First Commandment
