In John 13, Jesus demonstrated to his disciples what role they have with one another and how they should live. We live on a dirty earth and we need to serve one another by confessing our sin and metaphorically washing each other's feet. As Christians we live in humble obedience to Christ and we look to Him who humbled Himself on the cross for our sins. We trust & believe in the finished work of Jesus Christ. Have you done that in your life?
