Because reality is hard to see. (Also see this thread). If we work on this premise, we can prevent deceiving ourselves by distinguishing the differences between God's work and blind nature's. One may walk around and experience one's fear rising in a pitch black room. Since mind is reality, you are transparent and your thoughts may become manifest unless one takes full control. According to Christopher Langan, we are transparent to the global conscious agency God, which means God is there in the room with us even in our most ignorant and fearful moments as God sees all. In regards to how and why God rarely responds to us I would think it is due to the fact that we must "go beyond" the everyday existence to reach Him and in return we may or may not be disappointed. I leave any further speculation on this matter to you the reader.
