Peter explains to other believers that God had shown him a vision telling him it was acceptable to preach to Gentiles. He recounts visiting Cornelius, a Gentile, where the Holy Spirit fell upon those listening before they were baptized. When questioned about this later, Peter recounts the vision and emphasizes that God had given the Gentiles the Holy Spirit, showing God had accepted them. The other believers then accept that God had granted repentance and salvation to Gentiles as well.
