The Archbishop of Canterbury and Presidents of Churches Together in England have called on churches to pray for peace and reconciliation to mark the 100th anniversary of National Day of Prayer starting on 4th August.
On 4th August, 1918 when King George V and Queen Mary joined members of the House of Commons and the House of Lords at the Church of Saint Margaret, Westminster; 100 days later the Great War ended.
Catherine Butcher from Christian charity Hope Together, which has organised the campaign, told Premier Christians should pray for "personal peace, peace in our families, peace in our nation and also in other nations".
She added that Christians can also use the 100 Days of Prayer as an evangelism tool.
"A huge percentage of the population say they pray at some time or another but they don't always know who they're praying for," she said.
"It's an opportunity for us as Christians to be talking to people during these 100 days and say 'do you pray?' and people mostly say 'yes' and when you ask people 'would you like to me to pray?' I've never had anyone say 'no don't pray for me'."
Buckingham Palace also recognise the significance of the National Day of Prayer.
