Acts 27:35

‘And when he had said this, and had taken bread, he gave thanks to God in the presence of all, and he broke it, and began to eat.'

Then he led by example and taking bread, deliberately and publicly gave thanks in the presence of them all, and breaking it, began to eat. This in itself was a kind of acted out prophecy. It was declaring the certainty that he, and they, would survive. Even in the midst of such extremity the habits of a lifetime persisted. He could not eat without remembering God and giving thanks. The likeness to the Lord's Supper is striking. What he was doing symbolised to Luke's readers that however severe the storms of life, by partaking of Christ men could be delivered from them and be saved.
