“But I’m not like those awful pagans!” (Jonah 2:8–9). That is why he was still susceptible to the spiritual crash that happened to him after God showed Nineveh mercy. He still felt, to some degree, that mercy had to be deserved, and they didn’t deserve it. We learn from Jonah that understanding God’s grace—and being changed by it—always requires a long journey with successive stages. It cannot happen in a single cathartic or catastrophic experience (like being swallowed by a fish!).
I.e, "so salvation comes partly from my good works as well..."
