John 3:13

And no one hath ascended into heaven, but he that descended out of heaven, even the Son of man who is in heaven.

Here Jesus claimed his unique office as God's messenger who descended to man out of heaven, and yet, in a sense, who was still in heaven. This verse, admittedly difficult, has led to the view that heaven is a state rather than a place, and that Jesus could say the Son of man was in heaven even while he was on earth. Another view supported by this is that during the personal ministry of Christ he continued in the full possession of his heavenly attributes. Still another concept that finds support is the doctrine of the ubiquitousness of Jesus. Dogmatism is out of order here, due to the textual questions regarding this verse. Westcott wrote that these words were "omitted by many very ancient authorities, and appear to be an early gloss bringing out the right contrast between the ascent of a man to heaven and the abiding of the Son of man in heaven."[15] In the International Version, this place reads: "No one has ever gone into heaven except the one who came from heaven, the Son of man."
