Hypothetically, of course, regardless of whether or not you believe in him. The construct known as "God" according to the Christian bible and/or Judeo-Christian belief system, in so far as the two do or do not conflate but their core remains similar. I am not seeking a philosophical debate about God, nor do I care for any philosophical "loopholes" which may exist. My question is straightforward and should only be answered within the confines of the aforementioned specifications. Also, I am not concerned by any real or perceived "flaws" and/or limitations within MBTI itself, and am only asking your opinion in accord with the Myers-Briggs typology system.
My answer: Yes.
I - Is an obscure entity who does not interact and correspond with his creations unless he is modifying them, or guiding them, and clearly spends an inordinate amount of time in solitude. Being an omniscient being, he must utilize self-reflection and internal rationalization in order to extract the desired course of action. He is independent and does not rely on assistance or immediate company, and as far as is claimed, he is the only entity of his stature in existence, which indicates a predisposition toward detachment from everything external of his own sentience.
NT - This is obvious, as he must clearly posses the qualities of an intuitive thinker as primary characteristics, who must process vast quantities of information through his own logical conduits before compiling the results in a manner that reflects his internal vision. To construct the entire cosmos would indubitably require abstract reasoning, logical analysis, and immeasurable conceptual abilities. The latter, in particular, seems to correspond well with the INTJ's Te/Ni combination, where Ni produces ideas and seeks possibilities, and Te organizes the resultant concepts in a logical manner.
J - The universe has structure and is governed by the laws of physics. God set rules and mandated a code of conduct. He clearly immersed himself in the affairs of mortals when they did not display the desired behaviors, and overtly expressed his disapproval, which required immediate resolution. God plans and sets goals for mortal men, e.g. reaching heaven. In other words: God seeks closure. In the INTJ, this characteristic is evident through the interplay of Te and J, where J demands structure, and Te demands the logical organization of the external universe.
