I'm not insisting you are wrong George, I'm just not seeing it. I do not see where any of the verses you quoted say Jesus is still a man.
Rom 8:3 For what the law could not do, in that it was weak through the flesh, God sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh:
The above verse shows what God thinks about the flesh including His Son's flesh.
Col 1:15 Who is the image of the invisible God, the firstborn of every creature:
Joh 14:9 Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Shew us the Father?
Clearly the Father is not 'sinful flesh'.
Joh 5:37 And the Father himself, which hath sent me, hath borne witness of me. Ye have neither heard his voice at any time, nor seen his shape.
Joh 4:24
(KJV) God is a Spirit: and they that worship him must worship him in spirit and in truth.
Ray says God is not 'a' spirit but Spirit period as Concordant and Rotherham show.
(CLV) God is spirit, and those who are worshiping Him must be worshiping in spirit and truth.
(Rotherham) God is, spirit; and, they that worship him, in spirit and truth, must needs worship.
If God is spirit and Jesus the Image of God then you can safely say it means the spiritual image, IMO.
Below are the verses you quoted and the Greek meanings from Strongs. I do not see where any of these say Jesus is currently a man.
