When the Timpview High School seminary council in Provo, Utah had the students write their testimonies and mailing addresses in copies of the Book of Mormon, Sean Dixon joined in, not thinking much of it until 1989 when a letter came in the mail from Pakistan addressed to Sean. Somehow, his testimony had made its way all the way to Stephen Anjum, a Pakistani Christian. Sean and Stephen became pen pals for seventeen years before meeting each other for the first time, and over the course of thirty years, Stephen’s missionary efforts spread like wildfire.
Sean grew up reading the Book of Mormon, and Stephen first read it in Pakistan in 1988.
