It debuted at number seven on the Billboard 200, number two on the US R&B Chart, and topped both gospel and country music charts. The album held the number one position on the Billboard's Gospel Album Chart for over six months since its release. Warryn Campbell produced the album and collaborated with many professionals: Kierra Sheard, David Banner, Marvin Winans, Daryl Coley, Andrae Crouch, The Rance Allen Group, Dorinda Clark Cole, Joe Ligon, Walter Hawkins, Tramaine Hawkins, and Karen Clark Sheard.
