God, the Invisible King by WELLS, H. G.

Wells wrote in his book God the Invisible King that his idea of God did not draw upon the traditional religions of the world: This book sets out as forcibly and exactly as possible the religious belief of the writer. [Which] is a profound belief in a personal and intimate God. Later in the work he aligns himself with a renascent or modern religion ... neither atheist nor Buddhist nor Mohammedan nor Christian ... [that] he has found growing up in himself. (Summary from Wikipedia)
