When Our Hearts Are Hardened
In his recounting of Jesus walking on water, Mark uses a curious phrase. He tells us that the disciples hearts were hard. That's a phrase that shows up a few times in the Bible; think of Pharaoh's heart. However, I think Mark is using this in a different way primarily to talk about a lack of imagination. All the ways that disciples miss the truly miraculous that's right in front of them. The Divine shows up in more ways than we know.
