At 19 years old, "Duck Dynasty" star Sadie Robertson has just made a lifetime commitment to print something on her left arm.

The reality star made the revelation of her "fearless" tattoo on her Instagram account (@legitsadierob) by sharing a cropped photo of herself driving. In the photo, the word "fearless" was seen scribbled on the side of her left arms.

She captions it: "I fully understand tattoos are not for everyone. Allow me to explain... for every summer camp I went to throughout my life I wrote down the word anxiety for my biggest struggle. Fear began to consume me. This year I made a turnaround when I went to my Lord and Savior who has conquered all fears."

When she started going to the 2015 Winter Jam, Sadie made the decision to give up all the fears in her life. "A new confidence and courage came every single night. By the end, all fear was gone," she shares. "I had people come up to me and tell me these words 'Sadie you are fearless' which was something so new to hear considering I am the one who has always struggled with FEAR! I decided that's enough. I am a fearless child of God. I will not fear, because I serve The God who has conquered all fear. I'm proud to permanently have a reminder that I have nothing to fear. I am fearless in The Name Of Jesus."

To honour her tattoo, Sadie then shared the Bible verses Ephesians 6:19 to 20: "Pray also for me, that whenever I speak, words may be given me so that I will fearlessly make known the mystery of the gospel, for which I am an ambassador in chains. Pray that I may declare it fearlessly, as I should."

And for those who are concerned how her parents Willie and Korie will react to the tattoo, Sadie told them to have no fear as well. "This was daddy-approved," she adds as a postscript.
