Richard Gamble believes God has given him a mission: to build a huge national monument, made from a million bricks, each representing an answered Christian prayer. It seems an impossible task for a sports chaplain who has no experience of construction. And yet over the past eight years, he's managed to pull together a project team, raise thousands of pounds and launch a global design competition with the Royal Institute of British Architects (RIBA). But before a single brick can be laid, they need to secure a site to lay it. Richard hopes lie in the Edmistons - a family multimillionaires and evangelical Christians, who own extensive land in the West Midlands. Will his hopes be realised? Will he find a home for the Eternal Wall of Answered Prayer? Producer: Becca Bryers
