Next to family, faith is the most important thing in "Duck Dynasty's" Sadie Robertson's life.

The 17-year-old reality star told FOX411 that she's grateful her family's success has allowed her a large platform to share her message of faith, which she does in her new book "Live Original."

"I think people use fame as an excuse to lose their faith," Roberston told FOX411 in March. "Faith is obviously my number one priority and I think you need to put God at the top of everything you do."

One area that her faith guides her is in her relationship with boyfriend Blake Coward.

"My boyfriend is very supportive of me publicly displaying my decision to stay pure until marriage," Robertson told Inside Edition. "I think it's also important because as teenagers we always get "the talk" from adults...it's another thing to hear about it from somebody who's going through it with you."

Robertson shared three tips on how to stay pure:

1) Don't be home alone together

2) Stay outside of each other's bedrooms

3) Pray together before dates

Follow these rules and put God on top for the perfect recipe for relationship success she said.
