This passage is “Jesus in the interrogative mode” as Bill Evertsberg has been putting it. This passage is more question than anything else. A flood of questions. A torrent of questions. A deluge. And it’s hard not to feel the exasperation of Jesus. His questions disclose his mood.
By the time we get to this scene in Mark 8, the disciples have been on a long journey away from home. They have been back and forth across the Sea of Galilee at least twice. If you’ve been on a boat ride across the Sea of Galilee, you’ll be able to picture this perfectly. On the boat ride over, Jesus calms a storm. On the boat ride back, he walks on water. On one side of the Sea of Galilee, Jesus feeds a crowd of 5,000. Then crossing back to the other side of the sea, he performs that same miracle again, this time for a crowd of 4,000. (That’s more people than fit in the Lyric Opera and the Chicago Theatre combined.)
