In John 13:1-20, Jesus shows us the heart of true service by washing His disciples’ feet. He serves because He loves, not to gain approval. His actions flow from a secure identity, knowing He belongs to the Father. Jesus models a humble posture, laying aside status to meet others’ needs. He reminds us that service begins when we first receive His grace, allowing Him to cleanse and restore us. He then calls His disciples to serve in obedience, following His example. This kind of service is not always easy—it is often costly, as seen when Jesus washes even Judas’ feet. Jesus concludes by teaching that blessing comes not just from knowing how to serve, but from actually doing it.
