During the Last Supper, Jesus—knowing He had full authority from God—humbly washed His disciples' feet to teach them a lesson in servant leadership, contrasting His self-emptying love with Judas's greedy betrayal and Peter's prideful resistance. This act symbolizes both the complete "bath" of salvation and the need for daily cleansing of worldly defilement, calling all believers to serve one another with genuine humility.
