Now that I, your Lord and Teacher, have washed your feet, you also should wash one another's feet. I have set you an example that you should do as I have done for you. I tell you the truth, no servant is greater than his master, nor is a messenger greater than the one who sent him. Now that you know these things, you will be blessed if you do them. And it's more than mere words and knowledge that disciples give each other.
Disciples give themselves to others.
Disciples serve each other by listening, supporting, encouraging, affirming, confronting, helping, loving, empathizing, and being there. Disciples are generous with their time and energy, imitating the One who knew how to serve. As servants, disciples learn how to be sensitive, to know when they are needed and when they are not needed. True servants can read people well. They can feel pain in others and know when to step in and help.
