If one defines God as everything that exists and our sense of God as a sense of connection and oneness with the totality of existence then by definition God exists. Of course a lot of people will disagree and that really is ego, the insistence on being separate and standing in opposition to what is or considering one’s self or one’s religion or group special. Religions mythologise the Oneness as God and the Separateness as the Devil but in making God ‘their God’ they introduce separateness and ‘their God’ becomes the Devil. Logically however, Oneness embraces Separateness and spiritually God embraces even the Devil. Understanding this and feeling it is the mystical or spiritual experience.
