One chapter later, God tells Jeremiah to go buy a clay flask—a finished vessel. Not raw clay on a wheel. A completed, fired pot. And God tells him to take it to the Valley of Ben-hinnom, in front of the elders and the priests, and smash it. … Here's what I want you to hold as we go: the difference between chapter 18 and chapter 19 is not the severity of the crisis. It's the condition of the material. Clay on the wheel is soft. It yields. It can be reshaped because it's still pliable. But a fired vessel—hardened, rigid, set in its form—when that meets force, it doesn't bend. It shatters.
