Before becoming a recording artist, Mason was a teacher in Michigan. She later relocated to Georgia in 1980 and continued in her teaching profession. In 1984, Mason left teaching and began the first stages of her musical career. In 1985 she received first place honors in both the songwriting and vocal categories at the Christian Artist Music Seminar in the Rockies. In 1988, Mason signed her first record deal with Word Records out of Nashville, Tennessee.
Mason taught music at East Cobb Middle School in the early eighties. She went on to pen chart-topping singles such as "Each One, Reach One" and "A World of Difference." Some of her songs have become church standards and songs such as "All Rise," "With All My Heart," and "Hallowed Be Thy Name" can be found among the regular song line ups in weekly church worship services. Her song "All Rise" was one of the most-recorded contemporary Christian songs of the 1990s. In 1996 album Heritage of Faith featured an arrangement of "Amazing Grace" which included excerpts from her late father's sermon recordings. The album also highlighted "Stop by the Church," written by Sullivan Pugh that earned Mason a Dove Award from the Gospel Music Association and featured a duet with her mother.
In 1999, Mason signed with Spring Hill Music Group and released "No Better Place". This project included the single "The House That Love Built," a song she co-wrote with longtime friend and veteran producer Cheryl Rogers.
Mason has always blended pop and contemporary praise, inspirational ballads, and soulful gospel into her music style. However, Mason had longed to record a 1940s-era project à la Billie Holiday, in which Spring Hill granted her wish request and recorded "Timeless" (2001). Highlights of this collection include "Theme on the 37th (He Can Work It Out)," a song written by Danniebelle Hall, an early Mason influence, and "Black and Blue," which was a poignant reflection on racism that Mason wrote with Turner Lawton.
Mason has performed before U.S. presidents, including Jimmy Carter, and sung at Billy Graham's evangelistic crusades. Appearing with Bill and Gloria Gaither and their "Homecoming Friends" at such major annual concert events as Praise Gathering and Jubilate. She has also been featured on several of their best-selling projects, including the Grammy Award–winning Kennedy Center Homecoming (1999). Mason is involved in Christian women's conferences and has been a very popular guest on the Women of Faith tour.
Mason has authored two books, "Treasures of Heaven in the Stuff of Earth" (2000) and "FaithLift: Put Wings to Your Faith Walk and Soar" (2003). She hosts a television talk show called "Babbie's House", which is broadcast on WATC-DT out of Atlanta, Georgia to a national audience as well as throughout Europe and Africa.
