Popular reality TV star Bear Grylls explains how to 'be still with God' in brand-new devotional book

Bear Grylls, famous for his survivalist antics while headlining reality show "Man vs. Wild," has revealed how he has learned how to "be still with God" in a brand-new devotional book.

What are the details?

Grylls, a British former SAS serviceman, said that the book spotlights "the most important part of his life," which is his "faith in Jesus Christ," according to Fox News.

The 45-year-old TV star, who has written more than 20 books on survivalism and more, said that the book began as a personal venture.

"I didn't really mean it to be public," Grylls said. "I wrote this book because I try to do something every day at the start of the day … and I've just written down notes over the years of things that have helped me ... where I secretly find my strength.

"It's rooted in Christ's teaching but it's all about love," he explained.

The book, titled "Soul Fuel," is a 365-day devotional. An audiobook of the feature is also available.

In the book, according to the network, Grylls writes, "I often don't feel very strong. Life can be a battle. We all feel that from time to time. But any strength I do have seems to come in the quiet moments at the start of my day. It comes when I am on my own, on my knees. It comes from taking time to be still with God."

"So," the book continues, "for me, starting my day like this really helps. It is like food. Like good fuel for the soul."

Another excerpt from Grylls' book reads:

Does God need us to be strong? No. Does He need us to be impressive? Definitely not. God is not wowed by our abilities. He goes where He is welcome and needed. He's looking for people who say a quiet yes to Him in their hearts. Those who can understand that alone we are so limited. When we are empty, He can fill us and work through us.
When we think we have it all in hand ourselves, there is no room in our hearts for Him to work His miracles.
Jesus said, "You are my friends ... I no longer call you servants ... I have called you friends " (John 15:14-15).
There is nothing more empowering — and no greater privilege in life — than to be called a friend of the Almighty. We are loved regardless, forgiven, restored, and befriended.

What else?

According to Faithwire, Grylls said that the message of faith is life's most important.

"You know, I've never met a strong person who hasn't had a hard road," he said. "And there is an element, I think, of faith when we're put under fire or we're scared or we're grieving or we're facing some illness or whatever, and in a way those are the times when the fluff gets blown away and the religious stuff gets blown away and the really important stuff, which is, 'I'm beside you, I will help you, I will hold you,' which is what the message of faith is."

He told Parade that his view on faith at large can be summed up in trusting the Lord.

"I hold onto the time when Jesus said he had come to abolish religion but bring life," he said. "Religion is a set of rules that confines but Christ was all about being set free and empowered. Faith to me is well summed up in the phrase, Facing All I Trust Him (FAITH)."

Grylls' latest book is available now wherever books are sold.
