Some people are appreciative by nature, but some are not; and it is these latter people who especially need God's power to express thanksgiving. We should remember that every good gift comes from God and that He is (as the theologians put it ) "the Source, Support, and End of all things." The very breath in our mouths is the free gift of God. Thankfulness is the opposite of selfishness. The selfish person says, "I deserve what comes to me! Other people ought to make me happy." But the mature Christian realizes that life is a gift from God, and that the blessings of life come only from His bountiful hand.
