Through his interactions with the Pharisees and his disciples, Jesus brings up three major questions that are worth answering. The first question that comes up is who people think Jesus really is. Peter responds that he is the son of God, and Jesus promises that he will build his church to which nothing will overpower it, not even Satan. The second question concerns the call of discipleship, and if people are willing to follow Jesus' radical call of self-sacrifice. The last question concerns the cost of not following after Jesus, which is the forfeiture of one's own soul as Jesus will ultimately judge people according to their deeds. People must make a clear decision on what they think about Jesus.
