Greetings Bradley D and Right Divider,
What is meant by the "Son of Man"?
"The crowd spoke up, "We have heard from the Law that the Messiah will remain forever, so how can you say, 'The Son of Man must be lifted up'? Who is this 'Son of Man'?" (John 12:34).
Jesus is both the Son of God and the Son of Man. The title “the Son of Man” first appears in Psalm 8, and this is stating that Jesus is a son of Adam:
Psalm 8:4–6 (KJV): 4 What is man, that thou art mindful of him? and the son of man, that thou visitest him? 5 For thou hast made him a little lower than the angels, and hast crowned him with glory and honour. 6 Thou madest him to have dominion over the works of thy hands; thou hast put all things under his feet:
Psalm 80:17 (KJV): Let thy hand be upon the man of thy right hand, upon the son of man whom thou madest strong for thyself.
Psalm 8 uses the language and framework of Genesis 1-3 and the creation of man to speak of the development of The Son of Man who would fulfil the role of Ruler over the earth, replacing Adam who failed. Jesus is the firstborn of the new creation.
The term "the Son of man" has to do with Christ's dominion over the earth.
Yes, I agree and Psalm 8 describes this, and 1 Corinthians 15 also teaches that Jesus will fulfil this role of "The Son of Man" as described in Psalm 8.
Different than the truth. The Jews were looking for a earthly Son of Man who would restore their Kingdom. Not a "Son of Man" who would be lifted up tp heaven.
Yes it is true that after his resurrection Jesus has been exalted to heaven to sit at God’s right hand, but the lifting up in John 12 is firstly speaking about his being lifted up in crucifixion:
John 12:32–34 (KJV): 32 And I, if I be lifted up from the earth, will draw all men unto me. 33 This he said, signifying what death he should die. 34 The people answered him, We have heard out of the law that Christ abideth for ever: and how sayest thou, The Son of man must be lifted up? who is this Son of man?
Kind regards
Trevor
