The explorer and TV presenter Bear Grylls has opened up about his faith during a recent interview. 

In an episode of The Diary of a CEO with Steven Bartlett, Grylls shared how his Christian faith has been "a real backbone" and a "secret of strength" in difficult moments. 

Bartlett had asked Grylls whether he got a feeling of fulfilment and achievement from climbing mountains and having success with his TV show. 

But Grylls said he found his sense of accomplishment from his Christian faith which had led him to be proud of "simpler things" such as being married for 22 years or having three boys. 

Although the 48-year-old adventurer admitted he found it "hard to articulate" his faith as he understands how religion has been "tarnished", he has always been vocal about it. 

He has previously been quoted saying his faith has been "a very empowering and important part of his life" and has various links with Holy Trinity Brompton (HTB).

Grylls was also famously seen praying for former president of the USA, Barack Obama during an episode of his TV show Running Wild with Bear Grylls. 

Grylls continued: "I was always the least religious person growing up.

"As I kid I had a really natural faith, I always believed in some higher power, I could feel there was something around and then I went to school, and we all had to go church and they all wore white cassocks and spoke Latin.It's been a life journey to unwind all of that and realise that actually the little me had it right. 

"Faith is in your heart, knowing that you are not alone. There's something bigger than us out there and therefore that power is for us and not against us and despite my doubts, I'm going to put my trust in that and try to have love at the centre of all we do, and live empowered and go for things and not be driven by fear."

A new season of Running Wild with Bear Grylls will be released in July, with celebrity guests learning essential survival skills.
