Horatius Bonar emphasizes the profound significance of Christ's act of washing the disciples' feet, illustrating His role as a servant and the importance of humility and service in the Christian life. He explains the distinction between being 'bathed'—representing our initial cleansing through faith in Christ—and the ongoing need for 'washing'—the daily forgiveness of sins as we navigate life. Bonar encourages believers to maintain their assurance of acceptance in Christ while regularly seeking forgiveness for their daily transgressions. He highlights that this understanding of grace empowers us to resist sin and serve others with love and humility, reflecting Christ's character in our actions. Ultimately, Bonar calls for a life of service that mirrors Christ's love and compassion for others.
