How do we know the doctrine of servanthood is true?

The doctrine of servanthood finds its foundation in the actions and words of Jesus Christ as recorded in the Gospels, particularly in Matthew 20:25-28. Here, Jesus instructs His disciples that true greatness lies in being a servant to others, contrasting the worldly view of authority and dominion. Additionally, John 13:12-15 illustrates Jesus washing His disciples' feet, emphasizing that no task is too low for a believer to perform for others. Servanthood is not merely a teaching but a lifestyle exemplified by Christ, who dedicated His life to serving humanity, even unto death. Thus, Christians are called to emulate Christ's humility and service as a reflection of their faith.
