The greatest saint in the world 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.
It is he who is most thankful to God and who has a heart always ready to praise God. This is the perfection of all virtues.
Joy in God and thankfulness to God is the highest perfection of a divine and holy life.
-- William Law (1686-1761), English cleric and theological writer.
Enter into His gates with thanksgiving, and into His courts with praise. Be thankful to Him, and bless His name. Psalm 100:4
