Amid nearly 4.5 million career album sales, numerous awards and consistent chart-topping radio success in an unprecedented six-year span, Casting Crowns lead singer and songwriter Mark Hall has never strayed from the group's main purpose: "Present discipleship through music."The band's message remains rooted in the youth ministry Hall has led on a weekly basis since 1999. The result with each new song collection is a fresh, relevant perspective on our journey with Christ. "Our main purpose, above all else, is to know Him more," shares Hall.It's this unwavering pursuit that has inspired Casting Crowns' latest release,

Until the Whole World Hears, an offering of encouragement, challenge, hope and truth to a world in need of Jesus. "As we travel through our journey as Christians, we come to a realization there are lots of people out there who need to hear about Jesus," Hall says. "Through our maturity, we begin to see the world as God sees the world and work with purpose to show people Jesus, until the whole world hears."
