If God is glorified in him, God will glorify the Son in himself, and will glorify him at once.
Morris observes that Jesus is expressing three certainties. The first is that God is glorified in Him, which means in the passion of Christ. The second is that God will glorify the Son in Himself, which seems to mean that the resurrection will follow the crucifixion and will be the “seal of approval” of the Father on the work of the Son. And the third is that God is going to do this without delay.
