The event, which featured a "Celebration of Hope" for all ages on Friday night and two events for young people on Saturday and Sunday, had a total attendance of 1,950, with 299 coming forward when invited to make a decision to follow Jesus.
Approximately 75 per cent of those who came forward were between the ages of 10 and 18.
In addition to his messages, Will brought greetings from his father, Franklin Graham, and grandfather, Billy Graham, who has a long history of ministry in the United Kingdom.
Throughout his time in the country Will was warmly welcomed by many people who recalled seeing the elder Graham preach in one or more of his many UK events, beginning with his Greater London Crusade at Harringay Arena in 1954 and ending with Mission England in 1989.
Prior to the opening night of Rock Thurrock, Will spent two weeks touring the United Kingdom and speaking to several different groups from Cardiff to Exeter, including a gathering of 1,000 leaders at Wembley Stadium at the Global Day of Prayer Carry The Torch summit.
"I've spoken with Christians and church leaders across the country, and they're all telling me the same thing," said Graham. "They all say that it feels like God is getting ready to do something big in the UK. They've seen things they haven't seen in 30 years, such as the level of prayer and unity in the churches."
Earlier in the week, a wide range of church leaders from the London area gathered to hear the news that Will's father, Franklin Graham, would be part of a large-scale evangelistic outreach in the UK. It is anticipated that the event will take place in London in 2013.
