In 2018, the Grays began their overseas ministry in Botswana. Bradley worked alongside a national minister doing Bible studies, counseling, visitor follow-ups, new converts classes and ministering in the community centers. Patricia taught a fourth grade class in a Christian school. As a family, they helped start a daughter work. Bradley and Patricia rotated preaching and teaching and worked with the youth, while their son Zachary helped with music. Patricia and son Patrick taught Sunday school and trained teachers. Even their son Noah preached a few times. They also evangelized throughout the country. After being appointed as associate missionaries, the Grays went back to Botswana and started a church in a new city. In less than a year, over forty were baptized and twenty received the Holy Ghost. Many Bible studies and new converts classes were taught. Noah taught Sunday school using an interpreter. Four different nationalities were represented in their church. Bradley and Patricia were appointed as intermediate missionaries in 2023 and will be going to Zambia. They will assist the Bible schools and children's ministries. They will also help strategize and implement starting churches in smaller villages and rural areas. Their passion is reaching the unreached people groups in this hugely populated country.
