What you see is not always what you get - and this true story of a man and his dog is no exception. Woven just under the surface of this simple parable, Keller presents profound spiritual truth. It is the story of Lass, a worthless animal thought to be untrainable, who becomes a magnificent and valuable sheepdog - not terribly unlike how God's love can transform our worst characteristics into blessings that serve to further His Kingdom. Allow yourself to see Biblical truth in this classic tale of what can happen when you yield to the Master.
