Reeves grew up in a musical household; her father, John Mark "Hershey" Reeves, was a musician, songwriter, engineer, and producer who had been working in music since the late '70s, and her younger sister, Mary Reeves, is a member of the group Only in Stories. When she was 15 years old, Reeves was attending a youth camp in Alabama when she experienced a spiritual awakening, and she committed herself to use her musical talents in the service of the Lord. Reeves became a member of her church's worship band, and began honing her skills as a singer, songwriter, and keyboard player. As Reeves became more experienced and confident as a performer, she began performing as a solo artist, and after opening a show for the alternative Christian group Plumb, the group's lead singer, Tiffany Lee (aka Tiffany Arbuckle), was impressed with Reeves' set. Lee introduced Reeves to the staff at the powerful Christian music label Sparrow Records, and in 2008 Sarah struck a deal with the label. In 2009, Reeves released a seven-song EP, Sweet Sweet Sound, and a three-song EP, God of the Impossible, followed in 2010.

In 2011, Reeves broke ties with Sparrow, and independently released her first full-length album, Broken Things. Christmas, an EP that featured new recordings of five beloved songs of the season, arrived in 2013, and the following year she released her second full-length album, Acoustic Worship Covers, Vol. 1. Despite having two releases of covers in her discography, Reeves was continuing to write songs, and her work was being recorded by artists such as Jesus Culture and Natalie Grant. In 2016, Reeves signed a new recording deal with Word Records, and her first album for the label was expected to arrive in the spring of 2017. ~ Mark Deming
