Christians have been giving Church unity the thumbs up at festivals in 2017.

More than 30 festivals will take part in the 17:21 campaign at different festivals throughout the year.

Over 120,000 Christians are expecting to take part in the campaign.

Gavin Calver, director of the unity for mission team at the Alliance and chair of Spring Harvest said: "It was amazing to see the 17:21 scroll unveiled on the first night of Spring Harvest earlier this year.

"We're excited to see the impact the commitment to unity displayed at festivals will have on the future of the Church in the UK.

"We're especially excited to see the impact that Church unity will have on churches seeking to make to Jesus known in their communities.

"We believe in Jesus' prayer that through Christian unity the world will believe."

Festival-goers are encouraged to add their thumbprint to the scroll which will then continue on to the next festival.

At Big Church Day Out, host Pete Greig invited the crowd to show their solidarity by raising their thumbs and by adding their thumb print to the scroll.

The 17:21 campaign is based on Jesus' prayer for his disciples in John 17 when he prays "May they all be one so that the world might believe."

The scroll has already travelled 3,000 miles and will visit Northern Ireland and Scotland later this year, likely clocking up more than 10,000 miles of travel.
