What does the Bible say about humility in serving others?

In John 13, Jesus demonstrated perfect humility by washing His disciples' feet, illustrating that to be great in God's kingdom, one must first be the least and serve others. This act of service was not merely ceremonial but one that exemplified His heart of faith and love for His brethren. The Savior's humility was rooted in His faith in the Father's promises, reminding us that our ability to humble ourselves and serve others stems from our faith in Christ. To truly serve as Jesus did, we must trust Him and believe in the transformative power of the gospel, which enables us to forgive, restore, and love others despite their shortcomings.
