The Seventh-day Adventist work at Zoissa started in 1977 through the families of Elder Ndumula and Elder Asheli Lusenga from Mghumbi. The two families from Kibaigwa village, Kongwa, Dodoma, some 58 kilometers away, had gone there for agricultural reasons. Upon arrival, they initiated Bible study with some people at Zoissa, which resulted in the conversion of Amon Kudel in 1979, who was subsequently baptized in 1980. As time went by, the number of baptized increased to 14.
