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. The work has been blessed the recent years and new churches in Mamelodi and Soshanguve-North have been instituted. Six missionaries are active in the Tshwane area. Church planting projects currently active are in Soshanguve-F4 (New Eersterust), Soshanguve Block UU&WW, Soshanguve Block XX&VV, Akasia (Living Hope) and in Nellmapius. The missionaries are assisted by theological students from the mission board.
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.
