Human nature tends towards exclusion, a mindset of “us” and “them”. This disposition existed in the time of the early church, where the gospel of Jesus first came to the Jews and was yet to be communicated to the gentiles (non-Jews). In this passage, we see Peter struggling with prejudice towards gentiles; but God miraculously revealed to him that the message of Jesus was meant for all people, even them.
Acts 10:1-48
