Peter responds with the answer that Jesus is the Messiah. This was not a concept at the time; the Jews were expecting God to return to deliver justice, but not expecting in the form of a man. Jesus warns the disciples of what is to come, and the pain He and they will go through to deliver mankind from sin. Imagine being a part of that conversation at the time of Jesus’s mission, with the apostles. Only Peter understood. We have the benefit of two thousand years of hindsight. Let us pray for others to understand, and to deepen our own faith.
