N.K.S.T stands for the “Nongu u Kristu u i Ser u sha Tar,” translated “Universal Reformed Christian Church,” a Christian Reformed church based in Nigeria. The church has its headquarters at Mkar-Gboko in Benue state but has spread all over Nigeria, and even beyond. The members are predominantly the Tiv speaking tribe but other tribes in Nigeria belong to this church.

It was first introduced in Sai on 17th April, 1911 a village in Katsina Ala local government area of Benue state, Nigeria. Although its headquarters is now at Mkar, Gboko, the local government is in Benue State.

The church is the fruit of missionary work undertaken by the Dutch Reformed Church in South Africa. Work began in 1911 among the Tiv people in then Gongola and Benue Province. The beginnings were slow — only 25 baptized Christians in 25 years. In 1960, due to the apartheid system, the South African missionaries were no longer tolerated in Nigeria and had to leave. In their place the SUM–Christian Reformed Reformed Church of North America, a branch related to NKST, gave it strong support until about 1985. In 1957 the church was formally organized as an autonomous, self-supporting, and self-propagating church with first four indigenous (Nigerian) pastors. A full translation of the Bible into Tiv was completed and dedicated on 4th November 1964. The church also has a synod that meets twice in a year.
