Last Sunday I did something I rarely do (at least in the United States). I preached. In the sermon I explore Jonah’s anger and our anger about injustice. I point out that the problem is not that Jonah is angry but that he is hardened and blinded. And then I end with the good news about how God relates to angry people and what he does to injustice.

I loved your sermon. It hit home on so many levels.
