John Chrysostom
He foretells two things: and second, that he had to stand before Caesar. He said the words, "God has granted you all," not from vainglory, but because he wished to convert those sailing with him. He said this not so that they would thank him, but so that they would believe his words.
"God has granted you all" was said to Paul. This expresses something like the following: they deserve death because they disobeyed, but this happens only by your mercy.
Then, after such a storm, he does not approach them with a discourse, but wants them to believe him in the future. He takes what had already happened to them as testimony to the truth of what will be said.
He adds two things: that they must end up on an island, and that the ship will perish, while the passengers will be saved. This was not a conjecture, but a prophecy, because he had to stand before Caesar.
