People get scared and lonely in life, but they're never alone, says Sadie Robertson

Sadie Robertson, the 18-year-old star of the "Duck Dynasty" show, is once again inspiring her fans with her Christian faith by encouraging people to trust in God no matter what they are going through in life.

"In life we get scared! We get insecure! We get worried! We get stressed! Sometimes we have anxiety! BUT we are not alone! We serve a God who is bigger than our fears, insecurities, & worries! He has already defeated it all at the cross. so trust that. Be brave & courageous because we have NOTHING to fear!" she wrote on her Instagram account (@legitsadierob).

It helps that Sadie is raised in a loving Christian home. Both her parents, Willie and Korie Robertson, have raised her and her siblings to love God with all of their hearts, and Sadie has done so every day of her life.

Living a Christian life does not come easy for Sadie, who has admitted that she struggles with jealousy and insecurity, and often compares herself to other girls. In a YouTube video entitled "Just Be You and Live Original," which has now received over three million views, Sadie shared her vital statistics and confessed that she "eats all the time" and that is why she does not have abs or a toned body.

"I'm just going to be straight up honest with everything," she said. "I struggle with jealousy, and I struggle with comparing myself to other people... I'm just like any other girl. I look in the mirror and I pick out a flaw."

However, one thing that helps Sadie overcome all of her body issues and other insecurities is God. She told other people that if they seek other people's approval, then they will never be happy. But if they form a personal connection with God, then they will find fulfilment.

"Don't look at somebody and say 'that's what I want to be' because in reality, if you're seeking self-approval or human approval you're never gonna reach your goal. You can only reach it by God," she stressed.
