Gratitude and thanksgiving forever stand opposed to all murmurings at God’s dealings with us and all complainings at our lot. Gratitude and murmuring never abide in the same heart at the same time. An unappreciative spirit has no standing beside gratitude and praise. And true prayer corrects complaining and promotes gratitude and thanksgiving. Dissatisfaction at one’s lot, and a disposition to be discontented with things which come to us in the providence of God, are foes to gratitude and enemies to thanksgiving.
