They went on from there and passed through Galilee. He did not want anyone to know it; for he was teaching his disciples, saying to them, “The Son of Man is to be betrayed into human hands, and they will kill him, and three days after being killed, he will rise again.” But they did not understand what he was saying and were afraid to ask him. Then they came to Capernaum; and when he was in the house he asked them, “What were you arguing about on the way?” But they were silent, for on the way they had argued with one another who was the greatest. He sat down, called the twelve, and said to them, “Whoever wants to be first must be last of all and servant of all.” (Mark 9:30-35, NRSV)
Is there someone in your world that you just can not image serving?
That one person if Jesus said to wash their feet, you might just walk away?
Now be honest, because if we are honest, we all have at least one person that we do not really want to serve in our lives.
Now do you have a good mental image of them?
And now picture yourself with them and Jesus, and Jesus asks you to wash their feet, and you do it.
That is what this verse says to do. To serve as Jesus served, remember that Judas was there when Jesus washed the disciples feet.
We must be a servant to all, because that is what He told us to do!
