John 13v14 Now that I, your Lord and Teacher, have washed your feet, you also should wash one another’s feet. 15 I have set you an example that you should do as I have done for you. 16 Very truly I tell you, no servant is greater than his master, nor is a messenger greater than the one who sent him. 17 Now that you know these things, you will be blessed if you do them.

We are called to serve others. Wash the feet, get dirty, place ourselves below others to lift them up to the hope in Christ. Christ came blatantly as a servant to set an example in flesh in blood how to love and how to live. Our greatest testimony is found in our service to others.
