The building began life as a mission house, built for Ersmark's newly formed missionary association after 1919 and inaugurated in November 1921. It served the community through decades of change, including a period of heavy wear after wartime requisition by the Crown, followed by renovations in the late 1940s and again in 1971, when a modern kitchen, toilets and central heating were installed.
In 1992 the mission house was extended and reopened as Ersmarkskyrkan, becoming a shared church run jointly by the Church of Sweden and the Evangelical National Mission Society (EFS), with EFS responsible for its day-to-day activities.
Today the church is a popular venue for baptisms and weddings, and its halls and gymnastics room are also used for children's parties and local association meetings, reflecting its continuing role as a community hub.
Inside, the altar textile known as "Vila och växande" (Rest and Growth), created by Lena Liljemark, depicts a sprout unfurling its leaves both upwards and outwards — a visual echo of the church's guiding themes.
