Savannah Guthrie holds fast to her faith as her mom’s life hangs in the balance

As Nancy Guthrie’s abduction nightmare stretches into a second week, “Today” show host Savannah Guthrie is desperately praying for her missing 84-year-old mother’s safe return — turning to her greatest source of hope and strength: the Bible.

“On Sundays, we’d spend all day at Casas Adobes Baptist Church for Sunday school, morning service, choir practice and night service,” Savannah told Guideposts, a non-denominational Christian magazine, in 2016.

“Faith was so woven into our daily lives, we liked to say that God was the sixth member of our family.”

Her mother, who was taken from her Tucson, Ariz. home on Jan. 31, was a no-nonsense single mom to Savannah and her two older siblings, Camron and Annie, after husband Charles suffered a fatal heart attack in 1988.

But one day, Nancy surprised her with a spontaneously kooky quest — and it’s become one of Savannah’s favorite memories.

“I was with her as she drove around doing errands,” said Savannah. “There was a rare desert rainstorm and afterward, a gorgeous rainbow arced across the sky.

“‘Is there really a pot of gold at the end of it?’ I asked. She replied, ‘I don’t know. Let’s find out!’ With me giving instructions, we drove around laughing and chasing the elusive end of the rainbow until the last wisp of color faded.”

In a poignant Feb. 2 Instagram post while praying for her mother, Savannah highlighted Isaiah 26:3 as the Biblical verse she has clung to for comfort in the midst of the family’s kidnapping horror.

“He will keep in perfect peace those whose hearts as steadfast, trusting in the Lord.”
