In 1930, three churches of the GKSA were formed in quick succession, namely in Gobabis, Outjo, and Aranos, after 1,922 Afrikaners left over from the Dorsland Trek were repatriated from Angola in 1929.
Near South West Africa, there were GKSA congregations in Humpata and Que, which were disbanded in 1928 over the aforementioned exodus of Angolan Afrikaners.
Services were held on the Omrah farm until June 20, 1959, when the church building finally opened along with the first Classis in South West Africa.
van der Merwe (pastor in Windhoek from 1950 to 1957, who was also responsible for Aranos), the church council obtained a parcel of land from the town.
Most members, especially the younger ones, worked avidly on the project since they wanted a church based where their children were in boarding school.
Dirk Postma founded the GKSA under a lilac tree in Rustenburg in the faraway Transvaal Republic, Dm.
The members worked hard to build the church under council guidance, especially a builder named Kiepie Erasmus.
The builders deviated from the architect's plan, however, for instance completing the concrete tower with cement bricks.
Aranos, Outjo, Biermanskool, Namib-Kus, and Khomas-Hoogland all seceded from the GKSA in 2016, by which time Otjiwarongo had already joined the Klassis Etosha.
