@FBM,
With regard to 'seeing' God:
We refer to him as a person, but in reality, he should more than likely be described as a 'force'. You would not see him, only his work.
As for some manifestation directed at you personally, you would have to experience it 'circumstantially' if that is the correct word. Thousands of years ago, he dealt directly with humans and we proved to be generally unmoved by his 'appearance', forgetting within a short time, as little as a few days, any vows made to serve him, whereas others proved faithful without such attention.
Today, we may read the accounts of such experiences and judge for ourselves what our reaction would have been. Under such a constraint, one would have to search vigorously to discover enough 'evidence' for belief. In my own personal case, the revelation that God's purpoae for man to live endlessly on earth provided sufficient motivation for such search. It took months; and I continue to evaluate my search even now, over 40 years later.
I don't expect to convince you with this short rant. I just wanted to show you how I got here.
