Gratitude

Would you know who is the greatest saint in the world: It is not he who prays most or fasts most, it is not he who gives most alms or is most eminent for temperance, chastity or justice; but it is he who is always thankful to God, who wills everything that God wills, who receives everything as an instance of God's goodness and has a heart always ready to praise God for it.
William Law
