One of the highest of human duties is the duty of encouragement… It is easy to laugh at men’s ideals; it is easy to pour cold water on their enthusiasm; it is easy to discourage others. The world is full of discouragers. We have a Christian duty to encourage one another. Many a time a word of praise or thanks or appreciation or cheer has kept a man on his feet. Blessed is the man who speaks such a word.

William Barclay, The Letter to the Hebrews.
