Trained To Be Moved By The Spirit
The Apostle Peter was on a training course. God was teaching him that Jesus has come to save everybody who would believe in Him, not only Jews. It was a difficult transition for the devout leader of the apostolic group. Like the others, he had been brought up to believe that Israel alone was God's people. Yes, non-Jews could be included if they converted, but otherwise Gentiles (everybody who was not a Jew) would always be excluded.
