Paul Sails for Rome
They went sailing. There was a lot of detail given about the route, but the point was, it took a long time. After a while they were in danger of getting caught some place which was not suitable to stay in the winter. Paul said the voyage from there would be dangerous, but everyone else went forward anyway.
It seems to me that they are setting Paul up to know that the way forward would be hazardous. But it seems that this is just true based on the situation. Yes, sailing from here will be dangerous, but apparently staying is not an option, so what else is there to do?
The Storm at Sea
There was a terrible storm and they were all in danger. Paul said that they should have listened to him. He also said that God talked to him and they would all survive but the ship would run aground on an island. There was also something about them fasting. Apparently they haven't eaten for 14 days and Paul says they should start eating again.
I wasn't quite sure how the fasting worked in to the story, but doing hard work and also not eating seems like a real bad idea. 14 days also seems very excessive, is that the point?
They hit a reef and the ship was basically destroyed. The soldiers wanted to kill the prisoners to make sure they didn't escape, but the centurion wanted to save Paul so stopped their plan. Everyone survived.
Seems pretty crazy to just kill the prisoners like that. I suppose it is not terribly surprising in such a primitive time.
