Sadie Robertson enjoys some Bible study with the girls

While most teenagers nowadays think that having a good time involves a night out partying with lots of drinks, Duck Dynasty star Sadie Robertson has a different idea on how to have a fun night with the girls.

The 17-year-old Robertson posted on her Instagram account (@legitsadierob) a photo of her and five other girls enjoying a Bible study session. The girls also had lots of sweet snacks during their Bible study, including Reese's Peanut Butter Kisses, M&M's, York, and Extra mints. They even took down notes using colorful Sharpies and neon-coloured paper.

"Great Bible study with great people," Sadie captioned the photo. "I encourage you to make something special for someone who is special to you. Let them know how much you appreciate them. Pass on love. Love your neighbor as yourself. Love is contagious. You never know how much a little thing can encourage someone."

It seemed like she shared the moment with her eldest sister Rebecca Lo Robertson, a Taiwanese student who was adopted by Willie and Korie, as well as future sister-in-law Mary Kate McEacharn, who is now engaged to her brother John Luke Robertson.

Rebecca just returned from her recent Taiwan trip, where she attended the wedding of her sister as a bridesmaid. She posted several photos of her trip on Instagram (@rebeccalorobertson) enjoying lots of Taiwanese delicacies and scenic views of the Asian country.

Sadie's brother John Luke proposed to McEacharn last October. He wrote about the whole experience in his blog and all the planning involved in the proposal and how he executed it. He added that some people are concerned that they are going to be married at such a young age but he argued that "a lasting marriage does not depend on when you get married. A lasting marriage depends on how forgiving you are and how much you love God Almighty. Those are the things that hold people together."
