“Peter saith unto him, Thou shalt never wash my feet. Jesus answered him, If I wash thee not, thou hast no part with me.” – John 13:8
Ephesians tells us that Jesus humbled Himself and gave His life so that He might sanctify and cleanse the church (the embodiment of His people) with the washing of water by the word that it might be presented to Him a spotless bride at his returning. We see this played out symbolically at His leaving, for we know from both the first chapter of the book of John, and the latter chapters of the Book of Revelation, that Jesus Christ was the Word made flesh. Therefore, at the last supper as Jesus prepared to leave, He (the Word made flesh) washed and cleansed His followers (the bride). Likewise at His returning, those who have been washed by the Word (Jesus) and are made spotless (free from sin) shall join Him once more at the Marriage supper if the Lamb.
“Husbands, love your wives, even as Christ also loved the church, and gave himself for it; That he might sanctify and cleanse it with the washing of water by the word, That he might present it to himself a glorious church, not having spot, or wrinkle, or any such thing; but that it should be holy and without blemish.” – Ephesians 5:25-27
“And the Word was made flesh, and dwelt among us, (and we beheld his glory, the glory as of the only begotten of the Father,) full of grace and truth.” – John 1:14 “Peter saith unto him, Thou shalt never wash my feet. Jesus answered him, If I wash thee not, thou hast no part with me.” – John 13:8
“And from Jesus Christ, who is the faithful witness, and the first begotten of the dead, and the prince of the kings of the earth. Unto him that loved us, and washed us from our sins in his own blood, And hath made us kings and priests unto God and his Father; to him be glory and dominion for ever and ever. Amen.” – Revelation 1:5-6
