In John we read, "If I, your Lord and Teacher, have washed your feet, you also should wash each other's feet. I did this as an example so that you should do as I have done for you. I tell you the truth; a servant is not greater than his master. A messenger is not greater than the one who sent him” John 13:14-16 (NCV).
Our whole lives should be spent serving others. Jesus was our prime example of what servant hood was all about.
