The church was built in 1940 to designs by the architect Johannes Dahl, and was consecrated on 1 July 1940 by Tor Andræ, then bishop of the diocese of Linköping. Bockara belonged to Mörlunda pastorate within the diocese of Linköping until 1973, after which it became part of the diocese of Växjö and Döderhult parish.
The timber building has a porch and entrance on its western side, a sacristy to the north, and a projecting chancel to the east. Inside, the walls of the nave are painted white, giving the small church a light, simple character typical of many Swedish parish churches of its period.
A renovation carried out in 1989–90 altered the chancel: the altar was brought forward from the wall so that services could be celebrated versus populum, with the priest facing the congregation rather than standing with their back to it.
On the right-hand chancel wall hangs the church's tabernacle, a reminder to worshippers of the presence of Christ within the building. A sculpture of Mary by Allan Lindholm, dating from 2006, stands near the eastern chancel wall.
The church has a pneumatic organ built in 1954 by Lindegren Orgelbyggeri of Gothenburg, later rearranged in 1983.
