On the highway leading into historic Trinidad, Cuba, is the Light of the South Baptist Church, located in the home of its pastor Asunción Sandovál Martins. The congregation of 20 concentrates on person-to-person ministries with children, youth, and adults.

Sandovál has been pastor of the church since its founding in 2003. Like most Cuban pastors, she is not interested in moving to a larger church. Her focus is on working with and ministering to the people who live within walking distance of her home and church. She feels called to be a witness to the people she has grown to love during her tenure as pastor in Trinidad.
