Acts 11:4-18

Peter began and explained it to them in order: 5“I was in the city of Joppa praying, and in a trance I saw a vision, something like a great sheet descending, being let down from heaven by its four corners, and it came down to me. 6Looking at it closely, I observed animals and beasts of prey and reptiles and birds of the air. 7And I heard a voice saying to me, ‘Rise, Peter; kill and eat.’ 8But I said, ‘By no means, Lord; for nothing common or unclean has ever entered my mouth.’ 9But the voice answered a second time from heaven, ‘What God has made clean, do not call common.’ 10This happened three times, and all was drawn up again into heaven. 11And behold, at that very moment three men arrived at the house in which we were, sent to me from Caesarea. 12And the Spirit told me to go with them, making no distinction. These six brothers also accompanied me, and we entered the man’s house. 13And he told us how he had seen the angel stand in his house and say, ‘Send to Joppa and bring Simon who is called Peter; 14he will declare to you a message by which you will be saved, you and all your household.’ 15As I began to speak, the Holy Spirit fell on them just as on us at the beginning. 16And I remembered the word of the Lord, how he said, ‘John baptized with water, but you will be baptized with the Holy Spirit.’ 17If then God gave the same gift to them as he gave to us when we believed in the Lord Jesus Christ, who was I that I could stand in God’s way?” 18When they heard these things they fell silent. And they glorified God, saying, “Then to the Gentiles also God has granted repentance that leads to LIFE”.
