James and John ask Jesus to sit at his right and left in glory. Jesus says they do not know what they are asking but will share in his suffering. He teaches that to be great one must serve others. Jesus came to serve and give his life for many. As his followers, believers should have the attitude of serving like Jesus through obedience to God and humility. Serving is a privilege that allows people to experience God's grace and power. Faithful servants will share in their master's happiness and receive rewards.
