John 14:22
This is the fourth interruption of the discourse by an apostle anxious to understand what was being said (cf. John 13:37, John 14:5, John 14:8); this time the speaker is Judas the son of James (Luke 6:16, Acts 1:13, who is also called Thaddeus Mark 3:18, Matthew 10:3.
Judas Iscariot had left the company some time before (John 13:30), but John is anxious that the name “Judas” shall not mislead.
Lord, why? ... Judas posed an important question. If Jesus planned to return mightily from death, why not use the opportunity to reveal himself definitively to the world and validate his power and identity? He was puzzled that Jesus would manifest Himself to them and not to the world.
Question: It seems often to us that Judas asked Jesus a good question; Why not show Himself to the world after His resurrection, why only to His disciples? What we do not know is what repercussions would have happened if the enemies now saw Jesus alive with His followers. They hated Him, didn’t believe who He was, nor would they accept His claim and teachings. They may have unleashed such a war and/or persecution against those also who followed Him and it would be so detrimental to the Truth and their cause. (For the extent of such persecution of the Jewish leaders against Christians, see note on Matthew 24:22; Mark 13:20 "unless those day had been cut short..." )
The disciples were still expecting Him to set up an earthly Messianic Kingdom and were greatly confused when He said, “the world will not see Me.” Jesus’ answer to Judas’ question in vv. 23 and 24 was that He will manifest Himself in the life of individual Christians and thereby the world will see Him through them!
He spoke of His death and His resurrection, by which He would appear again to His Apostles, but not to the worldly and unbelieving Jews. But Judas did not understand these words, and asked that they might be explained. The Lord answers him, Because these love, but the others do not love. Judas uses the word manifest, because Christ had just used the same expression, saying, I will manifest Myself to him.
