John 12:20-24

answered

He does not receive these Gentiles. A Christ in the flesh, King of the Jews, could be no proper object of faith to the Gentiles, though the Jews should have believed on Him as such. For Gentiles the corn of wheat must fall into the ground and die; Christ must be lifted up on the cross and believed in as a sacrifice for sin, as seed of Abraham, not David John 12:24,32; Galatians 3:7-14; Ephesians 2:11-13.

Son of man(See Scofield "Matthew 8:20").
Except

Chapters 12-17 are a progression according to the order of approach to God in the tabernacle types: chapter 12., in which Christ speaks of His death, answers to the brazen altar of burnt-offering, type of the cross. Passing from the altar toward the holy of holies, the laver is next reached Exodus 30:17-21, answering to Chapter 13. With His associate priests, now purified, the High Priest approaches and enters the holy place, in the high communion of Chapters 14-16. Entering alone the holy of holies John 17:1, the High Priest intercedes. (Cf) Hebrews 7:24-28. That intercession is not for the salvation, but the keeping and blessing of those for whom He prays. His death (assumed as accomplished), John 17:4 has saved them.
