When considerable time had passed and the voyage was now dangerous, since even the fast was already over, Paul began to admonish them to not continue, because he perceived that not only would there be a loss of the cargo but also of their lives.

Good morning. So Paul says that he didn’t come with an arrogant attitude but: I was with you in weakness and in fear and in much trembling, and my message and my preaching were not in persuasive words of wisdom, but in demonstration of the Spirit and of power, so that your faith would not rest on the wisdom of man, but on the power of God. When you read Paul’s words in all of his letters, he doesn’t sound like he was in fear and in much trembling; and he even mentions that fact specifically later. He didn’t just have a bunch of pretty words; but he had words ignited by the Holy Spirit that produced salvation in the listeners, confirmed with power. My Bible says that the Greek word translated demonstration is used of producing proofs in an argument in court. I guess you could say that Paul was the Perry Mason of the gospel. Father help us to have Your words and not ours when we speak to others about salvation. Go with your people during the coming storm. Move and control it so that it does not harm them or their property.
