And no man hath ascended up to heaven: A reference to His future ascension into Heaven after His resurrection
but he that came down from heaven: Referring to His incarnation
even the Son of man which is in heaven: In spirit, Christ during His incarnation, stood before the Throne of God in Heaven, even as Elijah did, or put it another way, although His feet were upon the earth, His mind was in Heaven, before the Throne of God. 1kings 17v1
Also note, during His incarnation Christ was NOT omnipresent! Phil 2v5-11
QED!

When Jesus said this, he literally meant what he said - no man had ascended up to heaven at that point. There are 2 ways to get into heaven, enter through the righteousness of Christ or work your way to heaven by never breaking the law. No one made it to heaven by works until Jesus came and fulfilled the law. He was the first to ascend to heaven. He was able to do this because he was God in the flesh.
I agree with you, Christ was not omnipresent on this earth. If Jesus said he was in heaven when he was actually still on earth then then the heaven he was talking about was not the heaven where the father resides. According to the bible Jesus brought the kingdom of heaven to this earth and that's the heaven the Son of man was talking about.
To me this passage affirms the fact that we now live in the kingdom of heaven and it helps me understand what the bible is talking about when it talks about "the kingdom of heaven". Many people mistake these bible verses about the kingdom as meaning heaven where God's throne is.
