Not to utter words, but to live by them

The one thing for such a person to do is to pray regularly, especially
at the actual time of temptation, and to throw the responsibility for
success upon God. He must carry on in this way, no matter how many
times he may fail; and, if he continues to pray, and especially if he
prays in the scientific way, he will, as a matter of fact, very soon find
that the power of evil has been broken, and that he is free from that
particular sin. To pray scientifically is to keep affirming that God is
helping him, that the temptation has no power against him, and
constantly to claim that his own real nature is spiritual and perfect.

-- Emmet Fox, Sermon On The Mount

As we express our gratitude, we must never forget that the highest
appreciation is not to utter words, but to live by them.

-- John F. Kennedy
