After starting his career in the late 1980s as a songwriter, Chapman has turned into one of the most prolific singers in the genre, releasing more than 20 albums to this date. Chapman has also won five Grammy awards and 56 Gospel Music Association Dove Awards, more than any other artist in history. His seven "Artist of the Year" Dove Awards, his latest in 2009, are also an industry record. As of 2007, Chapman has sold more than 10 million albums and has 9 RIAA-certified Gold or Platinum albums.

Chapman is also a vocal advocate for adoption, along with his wife Mary Beth. Together, they have adopted three children from China and have started a charity organization called Show Hope (formerly called Shaohannah's Hope), that mobilizes individuals and communities to care for orphans through its international orphan care work as well as adoption aid grants to help put more orphans from overseas and the U.S. in loving, forever families. In 2009, Show Hope finished building Maria's Big House of Hope, a medical care center in China that provides holistic care to orphans with special needs. He is also a contributor to Compassionart, a charity founded by Martin Smith of British rock band Delirious?.
