Written by Matthew Thompson
9 “Then, Lord,” Simon Peter replied, “not just my feet but my hands and my head as well!” 10 Jesus answered, “Those who have had a bath need only to wash their feet; their whole body is clean. And you are clean, though not every one of you.” 11 For he knew who was going to betray him, and that was why he said not every one was clean.
Before eating the Passover, the disciples would have taken part in a ceremonial washing in order to be purified clean to eat the supper. Since this would have taken place somewhere else, they would have then had to walk to the upper room across dirt roads in their sandals. The sand and muck of the roads would have made their feet dirty, but the rest of their body would have still been clean. In moving from speaking of the physical world to speaking of the spiritual world, Jesus made two points. One is that only He could bring salvation. The sacrificial system of the Old Testament was about to be replaced by the sacrificial death of the Son. Second, that even after we have been made clean, we still have to walk through a world that isn’t.
To be clean and to remain a part of Christ, we must to consistently dwell with Christ and allow the Holy Spirit to cleanse us on a daily basis. When you strip away all the big words and fancy theological concepts, that is the true essence of holiness. It is the daily surrender to the Holy Spirit that says “whatever contamination I have picked up on my journey in this world I fully surrender, and I know that ONLY in you, can I be made fully clean.”
