This week, we move forward to another prophet and another parable—Isaiah’s “Song of the Vineyard.” Nathan’s story exposed one man’s guilt; Isaiah’s song laments the unfaithfulness of an entire nation. Both reveal the heart of God: a holy love that longs for righteousness but grieves over rebellion.

David had sinned, and he knew it. He had taken another man’s wife, arranged a murder to cover it, and then carried on as if nothing had happened. Perhaps in the busyness of his royal life, he thought it was hidden away—buried in the past, forgotten even by himself. But God had seen it, and God sent Nathan.
