Savannah Guthrie, co-anchor of NBC News' "Today" show, is out today with "Mostly What God Does," a candid account of her connection to God and a gentle invitation to "come as you are" to faith — all told with what she calls "nothing but my curiosity and a receptive heart."

Why it matters: The book "is by far the most personal and vulnerable thing I've ever undertaken," Guthrie, 52, tells Axios. "I'm way out of my comfort zone. But I just felt like I had something good to say about God and couldn't help but share it."

"At church," Guthrie writes, "my pastor always apologizes when he tells the congregation a personal story or life anecdote that he knows they've heard from him before. 'I'm sorry!' he says sheepishly. 'I only have this one life!' In a way, I feel the same":

Behind the scenes: Axios hears Guthrie wrote this on a journalist's speedy timetable. Her publisher gave her a date two years out — and the book is on shelves in less than a year.

• Guthrie hates projects hanging over her head — one reason she's in daily journalism even though she has a law degree from Georgetown

Spoiler: Guthrie writes that mostly what God does is love you.
