In Acts 10, the Lord gave Peter a fascinating vision. God showed Peter all kinds of unclean animals and asked him to kill and eat them. He refused, saying that he had never eaten anything unclean. Nevertheless, God gave him permission to eat, saying he should not call anything unclean which God has made clean. God’s words were not merely referring to unclean animals; God was guiding Peter to preach the gospel to the Gentiles, whom the Jews deemed impure.
