Thanks Stephen. Actually, I think that the fear of the disciples was very reasonable, whichever way you look at it! They knew the lake/sea, and how dangerous the sudden storms were. On the other hand, they saw how peacefully Jesus was sleeping. I don’t think they believed he was the divine Christ, but they might have believed he could handle the storm if they asked him. I don’t believe he expected them to rebuke the wind and waves.
In the end, two different perspectives on the situation collide. It gives Jesus the opportunity to show the disciples that “even the wind and the waves obey him”. (No mention of demons, by the way). He was in control of creation, bringing order into its disorder.
I am further away from you over the healing of the demoniac. It would be a fair question to ask why Israel seemed to have such a high incidence of demonisation, about which even Jesus seems to find Israel culpable - Matt. 17:17. But he never blames the afflicted, and it is never attributed to Israel’s limited view of God.
Does your use of the phrase Firstborn Son of Creation indicate something about your Christology that we should know about?
