The Bible often uses everyday language and pictures to help us understand the reality that lies behind not only our lives but also our salvation. Jesus has shown us his power and identity as God-incarnate through the signs of his miracles. These displayed the reality of who Jesus was. As Jesus washes his disciples’ feet, he gives us a sign that is meant to display the reality of what Jesus does. Whereas we might expect to see a picture of the Passover Lamb, John gives us instead a foot washing. Buy why? Today in John 13, we have a wonderful picture of the great work of Jesus in our lives: his unmatched ability to cleanse us completely from our sin and guilt!
