I. The Washing (1-11). The time. Just before Christ's last Passover. Supper being "at hand" (Revised Version); washing taking place before a meal (St. Mark vii. 3). Always known as the "Last Supper" or Passover Feast. His "hour" for showing Himself fully as the Saviour was now come.
The cause (ver. 1). Love passing all knowledge (Eph. iii. 19). Shown by its greatness—loved to the uttermost; its comprehensiveness—including even Judas; its lowliness—doing a servant's work.
The act. Disciples began to dispute which should be the greatest (St. Luke xxii. 24). Christ shows by His action what His opinion is. The greatest in His kingdom are they who serve most. Takes towel, water, basin; washes feet of each in turn. Who declines to accept the act of service? But unless Peter submits to Christ, can have no part with Him. He dreads separation from Him, therefore is eager now to be wholly washed. Christ tells him two things—
(a) He cannot understand meaning of this act but will hereafter—will add to his faith, virtue (or valour), and knowledge (2 Pet. i. 3).
(b) He who is washed, i.e. bathed (Greek), in Christ's atoning blood (Zech. xiii. 1) needs only to "wash" or be washed from daily sin to be kept clean and holy.
II. The Meaning (12-17). Equality in Christ's service. He is their Master, but delights to serve them. Followers must copy His example.
Service. The spirit of His example to be followed—feeding hungry, teaching ignorant, visiting the sick and sad (St. Matt. xxv. 35, 36).
Knowledge. Life's mysteries to be cleared up hereafter. Duties now, rewards future.
Lesson. Lord, what wilt Thou have me to do?
Kindness to the Poor.
