 God Almighty, in human skin, washed the apostles' feet. Biblically, we were supposed to follow the same example. Now, granted, we wear shoes these days. Back in those days, people walked around with open-toed, open-foot sandals, and people needed their foot washed to come into the building. I don't know what it would be today. I suppose we could think about it and find something, but I find it interesting because I don't know if you've ever had your feet washed
