Acts 10:1-23

A centurion named Cornelius, after seeing a vision from God sent men to get Peter. As the men were on their way, Peter had a vision from God showing him all manner of animals and telling him to kill and eat. Peter responded that he couldn't because they were unclean, but God responded that He had cleansed them and they were no longer unholy. After this, Peter was told by the Holy Spirit that the men who had come for him were downstairs. He went to greet them and invited them in.

God may sometimes give us instructions that don't make sense to us. In cases where this happens, understand that God sees far more than we could ever comprehend and He always has a reason for the things He tells us to do. It is not our place to question God. We just need to listen and obey.
