Jason and Cintia Kumalo

Jason and Cintia Kumalo have served as house parents for Eric’s House, an in-home facility for orphaned or abandoned children and young adults, since 2013. Currently there are 30 kids ranging in age from 10 – 27 in their care. The older residents are completing higher education or receiving job training, but they still call Eric’s House home and consider Jason and Cintia as their guardians and parents.
Jason and Cintia say this about their life at Eric’s House:
"As house parents we deal with the day-to-day lives of these young adults just as any family would. We give them education and a safe environment to live in. We share all aspects of their lives from school, to heartaches over broken relationships, to triumphs in life goal accomplishments, to dating issues, to answering questions about faith and the purpose of our lives, to connecting with them and developing a relationship that will help us all grow as we daily strive to live for the kingdom. We laugh, we cry, and we live as a family."
Jason and Cintia have initiated several projects to increase the sustainability of the orphan care ministry at Namwianga. There are garden plots to provide vegetables, and poultry and livestock production for meat and eggs. The latest addition is a workshop where kids can learn light metalwork and woodwork for basic life skills that they can carry with them for a lifetime.Jason and Cintia do not have a sponsoring congregation. They love the work they are doing, but in order to continue and they need a committed church community to support them financially.
