When Jesus was with us, bodily, still then his divine nature did not cease to be, it did not cease to be a divine nature, and possessed of every facet or attribute of divinity. That is, he (the Person) did according to his human nature what was proper to it, and he did according to his divine nature that which was proper to it. So, for example according to his divinity, Jesus was still upholding everything in the universe (work he had done since Creation) while he was walking on dusty roads in Galilee in his humanity. Each nature was perfectly expressed in whatever environment it was found. The human did not directly express divinity; nor did the divine directly express humanity.
Jesus humanity did mediate certain aspects of divinity, i.e. miraculous power, the power to take his human life back again in resurrection, knowledge of the heart of others. In general, we recognize that Jesus' mediated divine exercise (as a man among us) flowed from his immeasurable anointing by Holy Spirit (Mt.12:28), the same Spirit he distributes (baptizes) to his people, Acts 2.
But there was a divine quality to Jesus recognized by his disciples, that he was more than simply one who was anointed "above his fellows," above any of the previous mediators (types) by Holy Spirit. He owned the divinity that rested with him. Those who spent time with him, whose faith was reposed in him more and more, eventually left behind all lesser thoughts concerning him (e.g. that he was a good man, a Spirit-empowered man, the best man ever, or even merely the greatest human possible); and they worshiped him as the incomparable Revealed God, as Emmanuel, as the Angel of the Lord.
What Jesus was then, he still is now. His human nature is in heaven--it has flesh and bone; it has spacial qualities: length, breadth, height, density, composition. He's there in body, and not here as he used to be--neither in Jerusalem, nor in London, nor in Buenos Aries, nor any other place. That is the message of the Ascension. "From thence he shall come to judge the quick and the dead," his humanity and his divinity together, "and every eye shall see him." His divine nature is everywhere (ubiquity, omnipresence); it has never been limited because it is divine, and his divinity is eternal, and he's never stopped being fully divine at any time.
Finitum non capax infinitum, the finite does not comprehend (contain, surround entirely) the infinite. Or to put it the other way: the infinite (his divinity) supersedes or goes beyond the finite (his humanity). But he, that is his Person, possesses both entirely, and so we confess it is not improper to speak attributively about him one way or the other, as per Act.20:28 and the blood of God (see WCF.8.7).
So, we should have no greater difficulties with Jesus' present state, and the hypostatic union of his two natures, than we would have had if we'd known him while he was still walking among us; than we know him in the Scriptures as the breathing, speaking Word of God.
Persons act, natures are, to use a classic formula.
