Northern Ireland joins 212 countries participating in this year's Global Day of Prayer. The Fermanagh event will take place at 7am on Sunday at Lough Navar View Point, and everyone is welcome.
The movement, which has spread worldwide since the first meeting in South Africa in 2005, brings Christians of all denominations together to repent and pray for their towns, nations and regions, on Pentecost Sunday.
Meetings range from secret gatherings in oppressed countries to huge stadium events.
Margaret Clarke, of Transformations Ireland, which organises the event locally, said: "We hope people across the island will go to their nearest meeting there are 15 in the North and three in the Republic this Sunday (11th).

"Every year it has spread, but Global Day of Prayer isn't about numbers so much as people joining together from different communities in heartfelt prayer for God's will to be done and communities to see transformation," she explained.
"We have seen incredible changes in this country in the last couple of years and we believe that these mass prayer events have played a part, along with the prayers of many others in bringing those about."
Again this year, events are preceded by 10 days of prayer and following the events on Sunday will be 90 days of Community Blessing when Christian groups will be actively looking for practical ways to help their neighbours.
