While Michael Gerson’s article in The Washington Post is more on politics than faith, he did mention how evangelical youth are fighting against modern slavery:

Those who think of evangelical youths as the training cadre of the religious right would have been shocked at Jubilee 2008, a recent conference of 2,000 college students in Pittsburgh sponsored by the Coalition for Christian Outreach. I was struck by the students’ aggressive idealism — there were booths promoting causes from women’s rights to the fight against modern slavery to environmental protection. Judging from the questions I was pounded with, the students are generally pro-life — but also concerned about poverty and deeply opposed to capital punishment and torture. More than a few came up to me between sessions in anguished uncertainty, unable to consider themselves Republican or Democrat, liberal or conservative — homeless in the stark partisanship of American politics.
