Book of Washington shall be the wonder of the world in this latter age for happiness and true hope, especially for those who are possessed with devils, and for those who are oppressed of the devil, and so forth, to the honour of our Heavenly Father, and the good of his Church, through Jesus Christ our Lord and only Saviour. Notwithstanding this true hope whereof I have spoken, the fruit thereof shall not extend itself save ye shall seek after it with your whole heart. See Preface 49-50.
