When Jesus offers to cleanse us do we refused to be cleaned? Peter lacked the understanding of this symbolic washing of his feet and at first refused. Jesus told him that he had no part of him unless his feet were washed. Then Peter said not just my feet but my whole body. Peter realized he was a sinful man that need the entire cleansing. Don't refuse Gods cleansing just because it just a small part of the bigger picture. God desires to cleanse us of all sin but does it in small pieces so we won't fall back into the same sin
He came to Simon Peter, who said to him, “Lord, are you going to wash my feet?” Jesus replied, “You do not realize now what I am doing, but later you will understand.” “No,” said Peter, “you shall never wash my feet.” Jesus answered, “Unless I wash you, you have no part with me.” (John 13:6-8 NIV)
