(Biographies) John Newton — John Piper
In this sermon, the preacher reflects on his experience of witnessing an eclipse of the moon and relates it to the darkness that Jesus experienced on the cross. He emphasizes the importance of illustrating truth in concrete language and not abstracting or generalizing, as this can lead to boredom and spiritual death. The preacher then discusses the challenge of bringing light into people's darkness, using the analogy of a two-watt light bulb in a dark room. He urges the congregation to examine whether they are more inclined towards tenderness or toughness and encourages them to focus on obedience in the midst of life's complexities.
