Jesus always acts as a single person, as he is both fully God and fully man, so not just switching back and forth in His natures, correct?David,
Belgic 19 may be helpful here:
"...yet each nature retains its own distinct properties. As, then, the divine nature has always remained uncreated, without beginning of days or end of life, filling heaven and earth, so also has the human nature not lost its properties but remained a creature, having beginning of days, being a finite nature, and retaining all the properties of a real body. And though He has by His resurrection given immortality to the same, nevertheless He has not changed the reality of His human nature; forasmuch as our salvation and resurrection also depend on the reality of His body. But these two natures are so closely united in one Person that they were not separated even by His death. Therefore that which He, when dying, commended into the hands of His Father, was a real human spirit, departing from His body. But in the meantime the divine nature always remained united with the human, even when He lay in the grave; and the Godhead did not cease to be in Him, any more than it did when He was an infant, though it did not so clearly manifest itself for a while."
