‘When therefore he had left Jesus says, “Now is the Son of Man glorified, and God is glorified in him. And God will glorify him in himself, and immediately he will glorify him'.
We have here a whole package of glorification. The Son of Man is about to be glorified, and God is to be glorified in Him. Then God will glorify Him in Himself, and will immediately glorify Him. This undoubtedly includes His being glorified on the cross (John 12:23-27) but equally clearly involves His restoration to the glory that had once been His in His eternal existence (John 17:5), by way of resurrection and exaltation.
This glorification of the Son of Man is described in Daniel 7:13-14. ‘I saw in the night visions and behold there came with the clouds of Heaven (out of a period of suffering) One like to a Son of Man, and He came even to the Ancient of Days, and they brought Him near before Him, and there was given Him dominion and GLORY and a kingship, that all the peoples nations and languages should serve Him. His dominion is an everlasting dominion, which will not pass away, and His kingship that which will not be destroyed.' Thus Jesus had very much in mind His entering out of suffering into the presence of the Father to receive eternal glory and kingship (compare Matthew 16:27-28; Matthew 25:31 ff; Matthew 26:64).
But His words here in John 13:31-32 go even further than Daniel, for they include the thought of His being ‘glorified in God Himself', something expanded on in His prayer in chapter 17 where He prays to be glorified ‘in the Father's own self, with the glory which He had with Him before the world was' (John 17:5). Thus He was not only, on behalf of redeemed mankind, to receive the kingship (Acts 2:35), and in His glorified manhood take His place at the right hand of God, but He was also to be glorified with the Father's essential glory, and take His place upon the Father's throne (see Revelation 3:21; Revelation 5:6). It is significant that as Glorified Man His place was at the Father's right hand, whilst in His Own divine glory His position was on the Father's throne.
Note that Jesus' statement is specifically connected with Judas' departure to carry out his Satanic purpose. Events of huge significance were now involved, and Jesus has given permission for them to commence. By His voluntarily allowing Satan's schemes to go forward Jesus has initiated the procedure which will lead to His full glorification, both on the cross, and then in His final Glory. And He was fully aware of the fact.
So by His words to Judas Jesus has accepted His destiny on the cross, and by it He is to be glorified (John 12:23-27), and God is also to be glorified in it (compare John 12:24-28), for He has willingly given His Son (John 3:16), revealing His love for men. In this way God commends His love towards us in that, while we were still sinners, Christ died for us (Romans 5:8). Nothing brings greater glory to Father and Son than the cross and what it was accomplishing.
But it would not end there. For God will further glorify Him, first in His own being (‘He will glorify Him in Himself'. Compare ‘glorify Me with Your own self, with the glory which I had with you before the world was' - John 17:5), a glory beyond our comprehension, and then by immediate resurrection and exaltation, when He will be lifted up to the glory of God. So in each step of humiliation, by washing the disciples' feet, by bidding Judas to go about his purpose, by willingly taking the way to the cross through humiliation and degradation, Jesus was being glorified, and God was glorified with Him. Jesus had to go through it step by step, and the Father had to stand back and watch, while supporting Him in His actions. And then, ‘immediately', will come the coronation and the final glory. The Son of Man will receive His kingly rule (Daniel 7:14), and the Lord of glory will receive back His glory (John 17:5)..
