On the surface, dancing the night away sounds like nothing to take seriously. If you look a little closer at the purity ball, however, you'll discover something special.

"Our young ladies have an opportunity to come out and make that committment publicly," said Deb Brittan, Sexual Health Education Director for the Ark-La-Tex Crisis Pregnancy Center.

Brittan says the commitment to abstinence until marriage is made with a father, or father figure, present who acts as a protector.

"One of the most important things for a young woman being to be able to keep a commitment of abstinence until marriage has to do with her understanding how valuable she is," Brittan said.

Along with abstinence, the girls have made a commitment to stand up for what they believe in.

"The truth is, virginity is just part of being pure," said 18-year-old Nicole Bonk, who attended the first regional Purity Ball in 2009, and will serve at this year's ball on January 28th.

Nicole and her sister, 16-year-old Rachel Bonk, who both attend Loyola College Prep in Shreveport, were interviewed in New York by CNN's Anderson Cooper about their commitment.

"I wasn't as nervous as I thought I would be I guess because of the prayer that we had going for us," said Rachel, who will also be serving at this year's ball.

"When girls are seeking purity they're seeking something that can enrich their entire life of who they are," Nicole said.

The Bonk sisters says their commitment involves embracing a pure path for their lives, physically, emotionally and spiritually.

Both girls are members of SWAT, or "Sisters Walking Accountable Together", a sorority for girls who have atttend local Purity Balls.

This year's event, "The Divine Dance", will take place on Saturday, January 28th at the Shreveport Country Club and caters to girls grades 7th - 12th.

The ball will include special music, a covenant ceremony and an opportunity for "new beginnings" for girls who have already become sexually active.
