The Nascimentos carry on a thriving ministry in Guyana, built on the foundation of American missionaries who were forced to leave by the Guyanan government.

Guyana is one of the northernmost countries on the South American continent. Guyana's colonial history has left the country with a diverse and interesting population: East Indians and Africans make up much of the demographic, while English is the official language. Because of the influence from India and Africa, people there practice Hinduism, Spiritism, and even Islam. Christians are in the minority. But yet, there is a remnant there and God is working to build His church in Guyana. 

In his kindness, God provided the people of Guyana a mature Christian witness from neighboring Brazil. Pastor João (John) and his wife and family live in Guyana and serve the people there as a pastor, Christian leaders, and as trainers for new believers in Guyana. Their ministry includes leading a Bible institute, which helps fill an urgent need to raise up more well-trained pastors and leaders to lead and plant more Guyanese churches. The Nascimentos also plan to train pastors and children's ministry leaders in their country how to effectively teach the Bible to kids by working with the Children's Ministry Training project.
