THE GOSPEL OF JOHN IV. THE DISCIPLES’ PREPARATION BY THE SON OF GOD (13:1–16:33) A. THE DISCOURSE IN THE UPPER ROOM (Jn 13:1 – 14:31) 1. The Prelude to the Betrayal (13:1-2) 2. The Washing of the Disciples’ Feet (13:3-17) 3. The Exposure of the Betrayal (13:18-30)
a. Jesus Divulges (vv ) Read Jn 13:19. ~ Here Jesus reveals His very heart. ~ He shows what a kind Savior He is. At the same time in this statement Jesus tells His disciples that when one reprobate turns his back on them, it should not be a good enough reason for them to be discouraged. ~ It ought, rather, to confirm their faith.
The careful groundwork Jesus here lays proved sufficiently strong to keep the disciples together. ~ They did not scatter immediately after the crucifixion. This phrase (Jn 13:19b) means that Christ is the promised Messiah. ~ The disciples must continue to believe.
Read Jn 13:20. This verse follows the thought of v. 16, where Jesus spoke of being a servant to the one who sent Him. ~ He would send forth His disciples so that whoever would receive them would receive Jesus and, in turn, receive the one who sent Jesus – God the Father.
When the prediction of v. 18 begins to be fulfilled, Jesus nonetheless remains the Messiah, the Son of God, clothed with authority to send out His ambassadors. ~ The very facts of the humiliation confirm His authority and the validity of their commission. ~ The very facts of the humiliation confirm His authority and the validity of their commission. ~ They will remain ambassadors for Christ.
At the same time the mission of Jesus is here assigned the highest theological significance, the most absolutely binding authority – the authority of God Himself. ~ Failure to receive Christ is failure to know God. And because His disciples represent Him to the world, their mission, their ministry, takes on precisely the same absolute significance.
~ God Himself through their preaching will be making His appeal to the sinner. ~ The statement applies to all time, andto every true ambassador for Christ (i.e., to every ambassador who truly represents Him and truly proclaims His Word).
Thus, in this verse, Jesus anticipates the commission of Jn 20:21, where the parallels between His own mission and the mission of His disciples are explicitly drawn. ~ To the same disciples after the resurrection, this became not only assurance that Jesus knew the direction He was taking, but also a foretaste of the commission that would consume them to the end of their days.
