United prayer has happened (and is happening) in many places. This small account of what happened in Hull in the 1860s has been an inspiration to work for similar and greater things now:“There were united daily prayer meetings in the port city of Kingston upon Hull, supported by the established church and the dissenting denominations. Numbers of people were unable to gain an entrance to the central meetings, and so, many places of worship were opened each evening for prayer. A monthly united prayer meeting attracted more than 3000. As usual a rising tide of evangelism followed, and campaigns were still crowding halls in 1865 to excess, necessitating the hiring of the circus, at which ministers of different denominations preached. Other very successful campaigns were carried on throughout the year 1865.” Taken from the Second Evangelical Awakening in Britain by J Edwin Orr Catching the Wave – a resource for 40 days of prayer.
