Jesus washed his disciples’ feet in order to demonstrate to them their need to serve one another. But it is also a demonstration of the service that he was about to perform. Out his very divine nature, Jesus serves and loves his disciples and calls us to participate in that very same love to draw others into the salvation that he is bringing to us through his sacrifice.
