I think to think of God, rather than by sex or static image, as a force that we perceive in a manner that is possible for us to understand, and is generally pleasing.
I think God will look different to every person, as no single image could be sufficient to visually represent him. To me, God might be an older gentleman who reminds me of my passed grandfather, which would comfort me. To another, God may be female because that is what that particular person interprets God to look like in their mind.
Besides, it's silly to assume that God would be tied down to just one form anyway. That kinda belies the whole all-powerful thing, dont' you all think?
