We live in a fragmented culture. There’s no consensus about the big questions of what’s right and wrong and true. Jeremiah is a prophet in this same situation—he lived and wrote in a fragmented culture.  One of the challenges of a fragmented culture is living in the cafeteria of different worldviews, religions, and systems of thought. It’s typical to respond by saying, “I don’t think anybody has the answer.” But Jeremiah shows us that this very statement is ignorant of how the heart works. Jeremiah shows us that we need to see three things about the human heart: 1) the radical faith of every heart, 2) the radical flaw in every heart, and 3) the radical cure for every heart.
