If there’s one thing reading the Bible has taught me, it’s the limits of the human mind. I often read a passage and ask myself, “Now where have I heard that before?” Sometimes I’m able to come up with an answer. Sometimes I’m not. And sometimes my mind makes up a wrong answer out of whole cloth. But today we’ve got just such a rabbit hole of recollection, all incited by Jesus’ mention of the sign of Jonah.
