John Piper explores the concept of mercy in a discussion based on Jonah 4:1–11. He examines why God rescues rebels, highlighting the transformation that occurs when mercy is received. This transformation is key to understanding how mercy received becomes mercy shown.

Piper's discussion delves into the biblical account of Jonah to illustrate this point. Further details about this discussion are available, including a video where Piper shares his insights on the topic, titled "Jonah and the People God Pitied".
