In Matthew 20, we are told of a couple of disciples who wanted Jesus to make them His right-hand men. They believed they deserved this "promotion" instead of the other 10 disciples. Jesus basically says to them, "You want to be a leader? Learn to serve! Don't you see that I came to serve and not to be served?!" What is in your heart? The devil's pride or Christ's humility?
