From Science and Health pg 3:22-24: Are we really grateful for the good already received? Then we shall avail ourselves of the blessings we have, and thus be fitted to receive more. Gratitude is much more than a verbal expression of thanks. Action expresses more gratitude than speech.

pg 3:27-32 If we are ungrateful for Life, Truth, and Love, and yet return thanks to God for all blessings, we are insincere and incur the sharp censure our Master pronounces on hypocrites. In such a case, the only acceptable prayer is to put the finger on the lips and remember our blessings. While the heart is far from divine Truth and Love, we cannot conceal the ingratitude of barren lives.

These citations are powerful instructions about gratitude. In all our striving we can work to remain consistent in reflecting Life, that is, to be more lively, vivacious, joyful, active; to be the expression of Truth, that is to be honest, faithful, reject falsehoods, and to be Love manifested, that is to be compassionate, be quick in separating false claims of all sorts from God’s children, His creation, express kindness, be selfless, slow to anger etc. in order to feel more of our God given completeness and satisfaction.
