Simply pray.
That's the invitation from church leaders this weekend who are suggesting that people get together tomorrow, wherever they are, in order to offer up prayer.
Thousands of people are taking part in the initiative, from a massive rally in Wembley stadium through to tiny groups in small chapels.
The Isle of Man will be taking part, with continuous prayer from the cathedral in Peel and Broadway baptist church in Douglas, with the whole event culminating with an hour of prayer at Tynwald Hill in St John's from 7pm to 8pm
Manx Radio's religious correspondent Judith Ley says it's simple idea to try and make a difference in what are challenging times:
Manx Care's 'Home First approach' sees high demand
Former church could be converted... back to church
Manx Concert Brass heads west
Isle of Man set for Remembrance Sunday
