This chapter of Acts shows God's Divine Providence in action, contrasted with His miraculous powers. We can usually identify a miracle in the bible because we know those things don't happen today. The way Peter was rescued shows God's power working miraculously. Herod's death, though caused by an angel of the Lord (Acts 12:23), did not exhibit the same visuals as Peter's escape from the prison. It was hidden from man's perception, just as Flavius Josephus' account indicates. These workings, hidden from man's sight and perception, are what divine providence is about. Even though "providence" is not a biblical word, the concept of the word permeates the living Word of God.
