I think that that is more about the narrative. Esa, really, has two personas, one is the man, the other, is the image, the nature, of G-d. Perhaps these two aspects of Esas personality are represented by what He is ''doing''. When He ascends into the air, for example, He is not a Galilean fisherman, lol; that is ridiculous, imo. He is clearly meant to be taken as a Deific character. When He shows His human traits, we are presented, the 'man aspect.
Though, even when we are presented the man aspect, we are also told that He is Deific. We know that Jesus is Deific throughout the entire narrative, we know this even before He is baptized, since He is honored from birth. There is nothing ''normal'' about His birth in Bethlehem, this is a Deific being throughout.
