"[God] experiences a deep, divine disappointment in us when we are ungrateful and when we are unwilling to confess God’s hand in all things. (D&C 59:21.) But it is because of what our sustained ingratitude does to us, not to Him."
"Our society is afflicted by a spirit of thoughtless arrogance unbecoming to those who have been so magnificently blessed. How grateful we should be for the bounties we enjoy. Absence of gratitude is the mark of the narrow, uneducated mind. It bespeaks a lack of knowledge and the ignorance of self-sufficiency."
"I ask this question: How often do each of us take time to meditate on the numerous blessings that we continue to enjoy and with a full measure of appreciation in our hearts express gratitude to the source of those blessings -- even unto God? ...
"Perhaps our lack of gratitude toward God is one of the most common sins among us. Doubtless we are all in dire need of repentance. We are too prone to accept the activities in which we engage as accomplishments of our own, not giving the slightest amount of credit to the One who blessed us with health, strength, opportunities, inspiration, and the ability to achieve. We feel that we individually made the accomplishment through our own superior brain power or physical strength. What conceited fools we mortals are!
"The Latter-day Saint of real stature and genuine greatness is one who in deep humility gets on his knees every day and thanks his Eternal Father for his numerous blessings. Through humble prayer and deep spiritual communion, he draws light into his soul from on high and is guided by the Spirit of Revelation, even the Holy Ghost."

"It has been said that the sin of ingratitude is more serious than the sin of revenge. With revenge, we return evil for evil, but with ingratitude, we return evil for good."
"The Prophet Joseph said at one time that one of the greatest sins of which the Latter-day Saints would be guilty is the sin of ingratitude. I presume most of us have not thought of that as a great sin. There is a great tendency for us in our prayers and in our pleadings with the Lord to ask for additional blessings. But sometimes I feel we need to devote more of our prayers to expressions of gratitude and thanksgiving for blessings already received. We enjoy so much. (God, Family, Country, Salt Lake City: Deseret Book Co., 1974, p. 199)."
