"Duck Dynasty" star Sadie Robertson has revealed that as a little girl, she prayed that God would give her a platform to reach others with the truth of the Gospel. However, she never expected God to answer in such a tremendous way.

The 19-year-old daughter of Willie and Korie Robertson has made a name for herself around the world as a model, author, fashion designer, and actress - to name just a few. Currently, she's gearing up for a 17-night nationwide "Live Original Tour" where she will be joined by her brother, John Luke, his wife, Mary Kate, cousins Reed and Cole Robertson, Reed's fiancée, Brighton Thompson, filmmaker Max Zoghbi, and his wife, Bonnie Kate, and Colorado movie theater shooting survivor Bonnie Kate Zoghbi. The tour has stops in San Antonio, Baton Rouge, Birmingham and more beginning Sept. 22.

"I remember praying when I was little, 'God just give me something, give me a platform, give me people to reach,' " Robertson told Rare. "I would have never thought that he'd give me this platform or this many people to reach."

She added, "Whenever I used to think, 'OK, what do I want to be when I grow up?' it was definitely not this. I never thought this would happen to me."

Robertson is also among the film cast for "I'm Not Ashamed," a new movie about the first student killed 17 years ago in Colorado at Columbine High School, Rachel Joy Scott, because she was targeted due to her publicly known Christian faith. Robertson will be playing Scott's cousin, the person responsible for her conversion to Christianity.

While she has been blown away by the opportunities God has given her, Robertson said she's learned it's important not to limit God or doubt one's own ability

"Whenever you decide that you can't limit yourself and that God can do amazing things ... he'll take you to places you never even thought you could dream," the "Dancing With The Stars" alum said in the video interview with Rare.

When asked if she feels pressure to succeed in spreading her message, the "Live Original" author said she simply hopes to glorify God in all of her endeavors.

"Honestly, I don't ... because when I came into this, I was 14 years old ... but I always knew that this would be something to glorify God," she told Rare. "My whole message is speaking confidence into the youth of America."

Robertson also frequently shares inspiring messages with her 2.7 million Instagram followers. Last year, she encouraged those struggling with insecurity, anger, frustration, and confusion to turn to God.

"He can redeem you," she wrote. "He will reveal himself to you in a way you have never seen Him before. you may be lost, but you can be found through God. He will restore you. if you are going through something.. which we all are. let me ask you something... what are you turning to?

"(I)s it a temporary fix? or is it even a fix at all. don't give up. God is waiting on you with arms wide open. you are loved. you are treasured. you are worth living. you have a purpose. you are a child the King," she concluded.
