That is just about 100% wrong.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.
They were correctly expecting the restoration of the kingdom. That is why they asked Christ about it after FOURTY DAYS of instruction regarding the kingdom:
Note that the Lord did NOT correct their understanding, but simply spoke about its TIMING.Act 1:3 KJV To whom also he shewed himself alive after his passion by many infallible proofs, being seen of them forty days, and speaking of the things pertaining to the kingdom of God:
Act 1:6 KJV When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel?
Also take into account other revelations from God, like this one:Act 1:7 KJV And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power.
That refers to the kingdom of Israel (i.e., the house of Jacob) on the earth. They were right to expect the restoration of the kingdom of Israel with Christ as King. The "throne of his father David" is the throne of the king of Israel.Luk 1:30-33 KJV And the angel said unto her, Fear not, Mary: for thou hast found favour with God. (31) And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name JESUS. (32) He shall be great, and shall be called the Son of the Highest: and the Lord God shall give unto him the throne of his father David: (33) And he shall reign over the house of Jacob for ever; and of his kingdom there shall be no end.
The term "the Son of Man" refers to dominion ON and OVER THE EARTH. Again, that is why the term NEVER appears even a SINGLE time in Paul's epistles. If you don't understand why, then you have a lot to learn.
