Open for All "Do not call anything impure that God has made clean." Act 10:15 Peter was praying on top of a roof. He fell into a trance, he saw the heaven open with all the animals. God told him to eat, but he refused as they are not clean in the old testament. However, God said” Do not call anything impure that God has made it clean.” So, Peter start to share gospel to all the nations and people.
