Chapter 14, the beginning of the farewell discourse. It’s likely that the Chapter divisions are misplaced so Ch. 14 should begin at 13:31, which not only takes a change of pace with the sending out of Judas but begins the emotional intensity dominating the farewell discourse. This emotion is important in Ch. 14, Jesus, with the occasional affection-full interruption is giving explanation, assurance, and inevitable goodbyes.
Jesus assures his disciples that they will follow him into his Father’s house, and his going away is inevitably for that benefit. Thomas does know the way; which is Jesus. The weight of v. 6 is enormous, Jesus is the way and one must follow him even to the cross. The way is paved in anguish and suffering.
However there is deep joy and assurance, for by the coming ‘helper’ they will be kept in Jesus and as Jesus is fully in the Father, they too will know the way to the Father. The helper allows prayer Jesus’ name, which mediates with the Father.
This discourse shows the unique way to God, this is not arrogant as it is immersed in footwashing and crucifixion attitudes, and it’s kept through the Holy Spirit.
