The plea comes as the search for two experienced climbers missing on Britain's highest mountain has been delayed by more bad weather.
Efforts to locate Rachel Slater, 24, and Tim Newton, 27, on Ben Nevis in the Scottish Highlands were suspended on Tuesday due to treacherous weather conditions.
Chris Denham, pastor at Hope City Church in Leeds, where Mr Newton's brother is assistant pastor has asked for prayer to help find the couple.
He posted a picture of the couple on Instagram with the message: "Please pray today for the safe return of Tim & Rachel (Tim is the brother of our Assistant Pastor, Ed Newton, in Leeds).
"Also pray for the weather to clear which is preventing rescue teams from searching at present and for all the family. Believing for miracles to be taking place on that mountain because God is Able!"
The missing pair, from Bradford in West Yorkshire, went climbing over the weekend and were reported overdue on Monday.
The Lochaber Mountain Rescue Team did plan to resume the search at first light on Wednesday but heavy snow, fog and blustery winds have forced the plans to stall.
Rachel Slater is a seasoned climber and a graduate of Manchester University, she is employed as an environmental consultant near Bradford.
Mr Newton, who is originally from Leicester, also lives in Bradford and studied physics at the Universities of Manchester and Leeds, according to his Facebook profile.
Anyone who was climbing or walking in the Ben Nevis area over the weekend and saw the couple is being urged to contact police on 101.
