Why are the disciples’ feet dirty?
Because they have been following Jesus.
Disciples were those who ‘walked in the dust’ thrown up by their rabbi’s feet.
The disciples’ dirty feet are a sign of their being disciples.
Jesus is no longer with us in body. And we wear shoes. But we are called to be disciples who make disciples. So, whose footsteps are you following in, as you follow after Jesus?
And who is following you?
Who are you learning from in the way of faith? (It takes humility to let someone wash your feet.)
And who is learning from you in the way of faith? (It takes humility to wash the feet of others.)
