The Gospel passage begins with the scene where the mother of James and John asks Jesus that her sons be given the two best seats in the coming kingdom. Jesus reminds the two disciples that they do not understand the implications of what they are asking. Sharing in Jesus' kingdom demands sharing his way to the kingdom, namely, the cup of suffering which he is about to drink in Jerusalem. While Jesus the Master can promise a share in his sufferings to his disciples, the giving of prominent places in the kingdom is something only the Father can do.
When the other disciples expressed their indignation towards James and John, Jesus uses the occasion to teach the disciples about service to others as a way of leadership in his community. The leaders of the world exercise authority in seeking personal glory and riches. However, leadership in the kingdom is modelled on the example of Christ's sacrificial death as a "ransom for many". Therefore, the way of true leadership is by virtue of service since a servant is one who freely puts him or herself at the disposition of others.
It is no wonder then that Paul describes Christians as being "common clay pots". An ordinary clay pot has to be used by someone for drawing or containing water. On its own, it serves no purpose. As such, we too are called to become "clay pots" - to be used by the Lord for His glory and for the good of others. With God all things are possible.
Lord, help me empty myself so that You may use me.
