There are souls in this world who have the gift of finding joy everywhere, and leaving it behind them when they go.
Happiness is a great power of holiness. Thus, kind words, by their power of producing happiness, have also a power of producing holiness, and so of winning men to God.
Kind words produce happiness. How often have we ourselves been made happy by kind words, in a manner and to an extent which we are unable to explain!
Kind words are the music of the world. They have a power which seems to be beyond natural causes, as if they were some angel's song, which had lost its way and come on Earth, and sang on undyingly, smiting the hearts of men with sweetest wounds, and putting for the while an angel's nature into us.
Kind thoughts are rarer than either kind words or deeds. They imply a great deal of thinking about others. This in itself is rare. But they also imply a great deal of thinking about others without the thoughts being criticisms. This is rarer still.
Many a friendship, long, loyal, and self-sacrificing, rested at first on no thicker a foundation than a kind word.
