The Convention, which runs from July 12 – August 1 in the Lake District town, is exploring some of the deep questions of life, and has invited apologists Ravi Zacharias, Chris Sinkinson and Roger Carswell, and Bible teachers Vaughan Roberts, Ian Coffey and many others to preach. The Convention also aims to make its programme helpful to Christians who bring non-believing friends and relatives with them in its third week.
