Rev. Mercado founded Serving Jesus Christ Mission in 1972, with the purpose of reaching the population of Beni, an area covered by the banks of eight rivers in the jungle of northern Bolivia. It has many communities, and so far SJC has reached 43 of them with the gospel. SJC now has 18 organized congregations in the area. Much of the work is done by boat, as missionaries take the Gospel and material help to riverside communities.
