This is the fourth time one of the disciples interrupts this final discourse of Jesus (see 13.37; 14.5,8). Again John uses the misunderstanding of one of Jesus’ hearers as a means of furthering the discourse. Only (Luke 6.16) and (Acts 1.13) mention this apostle with the name Judas. The evidence for identifying him with Thaddaeus of Mark 3.18 and Matthew 10.3 is inconclusive.
Here Judas picks up the word reveal used by Jesus in verse 21. In this question the phrase to us appears first and so is to be stressed. It stands in contrast with to the world, which appears last in the Greek sentence order. The verb “to reveal” suggests a visible manifestation of Jesus in his final glory, and Judas does not understand how this manifestation can take place without being seen by the whole world. In reply Jesus indicates that the revelation of himself to his disciples is an internal, spiritual experience, which is dependent upon their obedience and love for him (see verse 23).
In some languages the question of Judas may be rendered “How can it be that you will cause us to see you, but you will not cause people in the world to see you?” However, to use a verb meaning “to cause to see” may not be adequate to render what is implied in the Greek term translated will reveal. The reference here is certainly to the glory which Jesus possesses, and therefore it may be appropriate to render this question “How is it that you will show to us how wonderful you are, but you will not show the same to the people of the world?”
