The importance of foot washing
During the last supper, Jesus rose from the table and began to wash His disciples’ feet. Joh 13:3-5. Through this activity, Jesus was establishing and fulfilling the principle of the laver. Prior to service in the tabernacle of Moses, the priests were to wash their hands and feet with clean water from the laver. If they did not wash before they approached the altar to offer up burnt sacrifices to the Lord, they would die. Exo 30:18-21.
Jesus said to His disciples that unless their feet were washed, they had no part in Him. Joh 13:8. He was telling them that they would have no participation in Him as members of His body; nor would they be part of the fellowship of His ministry of priesthood. Although they were unable to fully participate in His offering at this point, Jesus washed their feet so that they could participate in the fellowship of His priesthood as far as the garden of Gethsemane. They could not journey with Christ beyond Gethsemane because Jesus had said, ‘Where I am going you cannot follow Me now, but you shall follow Me afterward.’ Joh 13:36.
The washings associated with the laver refer to receiving the washing of the water by the word. We know this because Jesus said, ‘You are already clean because of the word which I have spoken to you.’ Joh 15:3. The word proceeds from the mouth of Christ as the sound of many waters. Rev 1:15. It sounds like many waters because it is the ministry of the word in the mouth of the many sons of God who are part of Christ’s body. The word flows from each person, according to their sanctification, as a ministry of the Spirit. The word is ministered to one another as the sound of many waters through body ministry at the communion gathering.
