Birmingham's blast furnaces relied on a constant supply of materials delivered by trains.  The newly formed iron products were in turn transported by railcars to factories.  Old steam engines required constant fuel to be shoveled into the boilermakers which made the steam which drove the pistons which pulled the freight.  God desires the whole city to be a Furnace of Prayer.  Mobile Prayer Furnace events are diverse worship and prayer teams pulling together as one train of worship to Jesus. Our favorite places to go are where hearts are really broken and hungry. That is often rehab centers for addicts and transition homes for people escaping crisis situations.  But anywhere wholehearted, night and day worship of Jesus is welcome can become a Mobile Prayer Furnace destination.
