Third Day was featured on last night's episode of 30 Days, an FX original series. The documentary program, created by Super Size Me director Morgan Spurlock, places people in an environment that is “antithetical to their regular way of life” for 30 days, according to the show's Web site.

In the episode titled “Atheist/Christian,” an atheist was placed to live for a month with a Christian family, who took her to a Third Day concert. The band's music and live performance was featured in the broadcast.

The episode debuted last night, and is scheduled to re-air Saturday at 2 p.m. EDT and Monday at midnight on FX. Check local listings for stations.
