I fdon't believe he was short. Or tall. Or middle height. I don't believe it matters and I've never seen a biblical reference where it indicated height.
I do believe that he radiated authority and wisdom, that he was a natural leader and teacher and someone who it was nearly automatic to defer to and respect.
None of that requires height. Aas you pointed out, with the blood of God flowingg in his veins he doesn't need the height advantafgghat the normal man might need. Do you really find it hard to believe that God could experience difficulty in making a midget a natural leader?
I don't believe size is relevant (Abnd for the record I'm not short myself). If you can find a more compelling Biblical comment re his height I'd be happy to re-examine it.
As to the topic of whether short people make tyrants rather than leaders, that deserves a whole page to itself. I would point out though that a: the average height has been growing steadily for centuries and many we don't think of as short would stand out for that reason today (Captain Cook, etc. Also, how many non-mythical leaders are famed for their height? c: At the times of Temuchin or Timurlane or Napoleon, etc how many world leaders were likely to have been taller? Or intrinsically better as leaders go?
Look .. I spent 3 years studying the Word of GOD - nobody can tell me GOD's own son would be anything but the most excellent specimen of humankind ever born. He would have been tall and strong .. yet calm and determined .. passionate and sentimental .. all at the same time.
In Eph. 4:13 - "Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ."
While I realize that scripture probably speaks of spiritual stature, I cannot imagine aspiring to a short "fulness of Christ" - you see my dilemma ..??
You can argue that all you want - but I'm already settled with it .. and I'm done discussing it.
