Sadie Robertson Wows 'DWTS' Judges as Her Family Reveals the Christian Sermons She Preached as a Child — and What Recently Made Korie's 'Jaw Drop\

Just moments before Sadie Robertson danced the Argentine tango on Monday night's "Dancing With the Stars," a video package aired featuring members of the her family sharing details about the "Duck Dynasty" star's Christian faith and praising the "well-rounded" woman she's becoming.

"I have a huge family," Sadie proclaimed in the package. "I mean, we take big family to another level."

Sadie's strong faith was among the elements discussed in the video, with her father, Willie Robertson, saying that her devotion to God was evident even at an early age.

"She was a great kid. Always super sweet," he said. "She used to do these little sermons up on top of the coffee table. And so she'd get up and preach to us."

A brief clip from one of those sermons showed a 5-year-old, pigtailed Sadie proclaiming that, "The most important thing in my heart is God."

Her grandmother, Miss Kay, added that the 17-year-old reality star has "always loved God" and has never been ashamed to talk about her faith.

As for Sadie's successful run thus far on "Dancing With the Stars," her mother, Korie Robertson, said that she initially assumed her husband would tell Sadie that appearing on the dance show was a no-go, but was stunned by his reaction. 

"I actually thought Willie would say, 'No,' so I told Sadie to ask her daddy, but Willie said, 'Well, you know you're 17 years old — if that's something you want to do, then I say go for it," Korie Robertson said. "And, I mean, my jaw dropped."
