The Jewish people of Jesus' day were very proud of their heritage and ancestry. Almost all Jews had no need for an entertainment program called "Who Do You Think You Are?" - they knew who they came from, physically, at least. Chris unfolds in this next passage from our series in John, that Jesus questions that heritage - a heritage all Jews trusted in. Chris leads us today to also consider who our forefather really is and do we truly acknowledge our spiritual father. As Jesus asked the Jews of His day: "Are you really genuine believers?".
