Through vivid, emotional storytelling and cinematic visual imagery, “Belief” illuminates the best of faith and spiritual practices from around the world — the rituals, stories and relationships that bind us all together as human beings. The series premieres on Sunday, October 18 at 8 p.m. ET/PT on OWN: Oprah Winfrey Network. And then, a mother who says her belief in God helped her through the worst day of her life — when her friend accidentally ran over her 17-month-old daughter and killed her. They tell Dr. Phil how the accident brought them closer.
