You can see in Book of Hoshea 12 verse 3 that the being that wrestled with Yaakov Avinu {Jacob}was God himself. [That incident is recounted in Genesis 32]. This leaves room for some questions. Could not God have won? Why did He find it so hard to wrestle with Yaakov who after all was only a man? And when the morning came God said "Let me go because the morning has come." ("I have got things to do?" Or maybe He has to work in the dark where his actions are hidden?). And He could not leave until Yaakov let Him go? You would imagine that God could leave any time he wanted--even if Yaakov did not let Him go.
And you can see that that being was God in the verses themselves where Yakov calls the place "pnuel" [the Face of God]. for I have seen God face to face and my soul was saved. [There is a danger in seeing the Face of God as the verse says "no man can see me and live."
What I am getting at is the idea of of the Kant -Fries School of thought that there is some area beyond what is accessible to human or even pure reason. That is the "dinge an sich." That is, there are two kinds of knowledge: (a) what can be checked--empirical and (b) what can not--a priori. Also two kinds of fact. Synthetic and Analytic. Analytic proven true by definition, and synthetic true but does not have to be true by definition. So what about Synthetic a priori like a figure can be formed by less than three lines. You can not make a figure with two lines. So how can u know if synthetic a priori is true? to Kant that is by structures in the mind. To Fries that is by immediate non intuitive. Hegel disagreed that this could be a true source of knowledge, but to me this makes sense--that Reason has limits.
This area of reasoning about God is one of those areas that is beyond reason--but still possible to know. See Kelley Ross's web site on the Kant Fries approach.
