"A man may have many acquaintances, but he will have few friends; he may count himself happy if he has one who will be faithful to him in time of trouble...Real friends are to be retained with great care, and, if need be, with great sacrifice. The wisdom of the world teaches this, and inspiration confirms it."(Source: Spurgeon's Sermon Notes)
