I can only tell you that in my experience he does speak and work in a way that is clearly supernatural. No it's not "whatever happens is him answering". It's probably better described as me breaking into reality, where I stop functioning just as an animal and become aware of his presence. In reality, he is present all the time, but we go about our lives as though he doesn't exist. When I talk about him breaking into our space and time what I really mean is that I momentarily break into the reality of his presence. His answer to a prayer is just him reaffirming to me that he is there. As for him being hidden, no-one can see God's face and live. But we can see his arm, for example, when he "works salvation" for us, in other words, he speaks or acts in a way that helps me but glorifies not me but him. (Someone gave a good example of a child hiding from its parent behind a lamp post. He/she thinks he is hidden but his Mum can see his arms poking out. Likewise, God is hidden, but he's hidden in such a way that we can know he's there because he's at work in the world)
