In July 20,000 people from across the UK will fill London's Emirates Stadium to hear the Gospel preached by international evangelist J John.
Just One is a mass-gathering the scale of which has not been seen in the UK since the visit of famed US evangelist Billy Graham more than three decades ago.
Taking place on July 8, the one-day arena event will feature J John, alongside music from Matt Redman, Hillsong, and the London Community Gospel choir, as part of a 'celebration of the relevance of the Christian faith'.
