One of the highest human duties is the duty of encouragement … It is easy to laugh at men’s ideals; it is easy to pour cold water on the 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
