The idea of oneness is a key component to Jesus’ prayer at several points in Chapter 17. The church is to be one so that the world might believe that Jesus was sent by God. The world can be described by what divides us. We see the division of mankind at every level: global, national, local, and even in families and close friendships. Sinful man is quick to divide. In this context, the church shows a unique unity in Jesus. It is an example to the world of God's power to save through Jesus Christ.
