3 Jesus knowing that the Father had given all things into his hands, and that he was come from God, and went to God;
4 He riseth from supper, and laid aside his garments; and took a towel, and girded himself.
5 After that he poureth water into a bason, and began to wash the disciples’ feet, and to wipe them with the towel wherewith he was girded.
6 Then cometh he to Simon Peter: and Peter saith unto him, Lord, dost thou wash my feet?
7 Jesus answered and said unto him, What I do thou knowest not now; but thou shalt know hereafter.
8 Peter saith unto him, Thou shalt never wash my feet. Jesus answered him, If I wash thee not, thou hast no part with me.
9 Simon Peter saith unto him, Lord, not my feet only, but also my hands and my head.
10 Jesus saith to him, He that is washed needeth not save to wash his feet, but is clean every whit: and ye are clean, but not all.
11 For he knew who should betray him; therefore said he, Ye are not all clean.
-Jesus, our Lord and Creator Himself, uses a great act of humility and service to illustrate an essential doctrine of Christian faith. Even for those who have been washed in His Blood, the very act of walking in the world stains us. We must continually seek the Lord to scrub away the filth represented here by dirty feet. Upon realizing that we must be continually cleaned to remain close to Jesus, our zeal could lead us, just as it did Peter, to request a full cleansing all over again. But once you have been fully cleaned-once you have been saved, you never need to be fully cleaned again.
