Note: I don't have a "picture" of God, nor any clue what God is or is not
BUT I experience that when I call upon or think a lot about Sai Baba or Jesus or Muhammad or... they appear in form or in vision or in dream.
Even when I repeated SoHum mantra silently in a Portugese Catholic Church for like 6 hours, during a ceremony where all others were chanting Portugese hymns (I don't speak Portugese hence I focussed on my mantra), Jesus appeared to me
So, again I have no clue about God, but when I follow instructions of Scriptures about God, things happen, and I like it, I feel immense Peace and Joy inside.
I call it God, being the source of all, without feeling the need to know or understand all the details, also because looking outside seeing the huge Universe, I kind of get the picture... it's way beyond my infinitesimal understanding, and I can live with that
