An educational wing was added and Sunday school classes began there on June 18, 1978. The education wing became the home of St. Paul's Christian School in 1979 and has grown to become Marion County's largest Christian preschool.
The congregation became self-supporting in 1980 with a membership of about 300. The church continued to grow, and a new sanctuary building was opened in August 1985. The occasion was marked by a complete reading of the New Testament by church members. A second wing was added to the education complex in 1998.
In 2014, a third building was added to the Christian preschool campus which now houses the school office, the Advanced VPK classroom, the school library and the children's kitchen.
The church's narthex (lobby) was expanded at the beginning of 2015 and is now almost three times larger and features hospitality and information centers, and TV monitors displaying information about the church and upcoming events.
