What does the Bible say about Christian humility?

In John 13:16-20, Jesus illustrates the principle of humility by reminding His disciples that the servant is not greater than his Lord. This passage follows Christ's act of washing the feet of His disciples, a task considered menial and beneath them. The lesson emphasizes that Christians must not be ashamed to engage in humble service or acts of kindness, regardless of the status of those they serve. True greatness in the Kingdom of God is indexed not by social standing or titles but by a willingness to love and serve others, even those deemed unworthy.
