 He increased in stature. He grew physically like every other child in the culture, moving into adulthood with a physical body, a physical body that would bear punishment for sin. He developed personally, increased in physical appearance toward maturity. He was not an emanation or just appearing to be in the flesh as some would argue. The docetics came up with that heresy where it was as if he was a ghost-like figure. The problem with that heresy is that none of the people that were around Jesus in his historical life said that.
