Puritan William Law.

The Puritan writer, William Law, considered a thankful spirit an essential quality of sainthood. He wrote: "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 alms or who is most eminent for temperance, chastity or justice, but it is he who is always thankful to God, who receives everything as an instance of God's goodness, and has a heart always ready to praise God for it."
