John 13 is a chapter that speaks to the importance of humility and service. Jesus, knowing that his time on earth was coming to an end, humbled himself and washed the feet of his disciples. This act of service was a powerful demonstration of Jesus' love for his disciples and a reminder that we should all strive to serve one another. Jesus then goes on to explain that if we want to be great, we must be willing to serve others. He also warns us against pride and reminds us that we should always be humble and willing to put others first. This chapter is a powerful reminder of the importance of humility and service in our lives. We should strive to follow Jesus' example and put others before ourselves.
