The FRCSA feel responsible not only for the preservation of the Church in South Africa, but endeavour also to expand the Church. The FRC Pretoria-Maranata is the sending church for mission work in the greater Tshwane area. Five missionaries are active in the Tshwane area. Church planting projects currently active are in Soshanguve-F4, Soshanguve Block UU/WW, Soshanguve Block XX and in Nellmapius. The missionaries are supported by a mission committee appointed by the church council.
Cape Town Area
After years of mission work a church has been instituted in Belhar. The mission work continues with church planting projects in Wesbank and Leiden. There are two missionaries active.
The local churches have evangelisation committees focusing on those who have become estranged from the Word of the Lord, trying to win them back for Christ. The FRCSA strive also towards reformation in South Africa.
