Acts 28
5 But he shook off the creature into the fire and suffered no harm. 6 However, they were expecting that he would swell up or suddenly fall down dead. But after they had looked for a long time and saw no harm come to him, they changed their minds and said that he was a god.

I am picturing a funny scene where all these natives are staring at Paul waiting for him to die, and Paul is just carrying on, and continuing to do what he had been doing.

Without modern medicine, things like a snake bite where immediate death. There was no antivenom. There was no ER.
Paul did not react in fear. He knew the healing power of his Lord, and his mission.

We can all use this same mindset. We can all practice this. God is no respecter of persons. That which He did for Paul, He can do for you! Live a life without fear while ministering the gospel.
