Our actions every day show the world who we are as a person. Your pastors set a great example. Them washing your feets is a great example of somebody knowing he is not above anybody. We are all the same. Some more fortunate with "wealth" of this world but in end all human beings who deserve to be treated equally no matter the statue.
It also carries a great a message. Here I have helped you by washing your feet, now you go out there and do something like this for someone else. Spread the help. That is what world should really be about. Helping each other. Unfortunately, people in power today, have forgotten all about that. And, it is on each and every one of us to change the trend by helping someone else each day. No matter how small it seems. :)
Another amazing post my friend. Have a blessed day. :)
