History
In 1747 Jonathan Edwards wrote a book, entitled: “A Humble Attempt to Promote Explicit Agreement and Visible Union of All God’s People in Extraordinary Prayer for the Revival of Religion and the Advancement of Christ’s Kingdom on earth”. Together, churches from across the UK and the United States committed to a long-term programme of extra- ordinary prayer for revival. They called it a 'Concert of Prayer'. It was hugely fruitful.
