…I hope that in Chicago the friends may become united and may illumine that city, for therein the dawn of the Cause appeared, and in this lieth its preference over other cities. Therefore it must be held in respect; perchance it may, God willing, be freed from all spiritual afflictions, and may attain unto perfect health and become a centre of the Covenant and Testament.
