Every January, tens of thousands of Christian college students from all over the world attend the conference Passion, where they sing, pray, and hear from a variety of pastors, authors, and activists about issues resonating within evangelical culture. For the last several years, conference founder Louie Giglio has made the issue of human trafficking an increasingly central part of these activities. In 2013, 60,000 students gathered at Passion in Atlanta for a late-night candlelight vigil dedicated to celebrating “Jesus, the ultimate abolitionist, the original abolitionist,” Giglio told CNN. The organization’s anti-trafficking project designated Feb. 27 as “Shine a Light on Slavery Day,” encouraging young people to raise awareness by taking selfies with red X’s drawn on their hands.
