In a poor Scottish home in the early 1800s, a father led his family in prayer. One of his sons would later write, “How much my father’s prayers impressed me…he poured out his whole soul with tears for the conversion of the heathen world to the service of Jesus, and for every personal and domestic need…As we rose from our knees, I used to look at the light on my father’s face…hoping that, in answer to his prayers, I might be privileged and prepared to carry the blessed gospel to some portion of the heathen world.”
