Albert Barnes Commentary John 13:32

"and God shall glorify him in himself, and straightway shall he glorify him." — John 13:32 (ASV)

If God is glorified in him. If God is honored by him. If the life and death of the Messiah are such as to lead to the honor of God, such as will manifest His perfections and show His goodness, truth, and justice, then He will show that He thus approves His work.

God will also glorify him. He will honor the Messiah. He will not allow him to go without a proper attestation of His acceptance and of the honor that God places on him. Jesus here confidently anticipated that the Father would show that He was pleased with what He had done. The Father did so through the miracles that attended His death, His resurrection, ascension, exaltation, and through the success of the gospel. We may remark that God will always, in the proper time and way, manifest His approval of those who live so as to promote the honor of His name.

In himself. Or, by himself; by a direct and public expression of His approval. Not by the ministry of angels or by any other subordinate attestation, but by an expression that will be direct from Him. This was done by His direct interposition in His resurrection and ascension to heaven.

Shall straightway. Immediately, or without delay. This refers to the fact that the time when God would bestow this honor on Him was near. His death, resurrection, and ascension were near.
