In 1898, a schoolteacher named Mattie Mallory felt God's call to care for orphaned children in Oklahoma Territory. A century later, siblings Carol and Albert Gray stepped into the legacy she began, finding a facility on the brink of closure. Moved by the children, their stories, and a deep sense of God’s calling, they knew they had to act. With unwavering faith and guided by their parents’ wisdom, they set out to continue the work. What followed can only be described as the miraculous work of God. A Legacy of Hope chronicles the remarkable transformation of Bethany Children’s Health Center through impossible financial challenges, organizational battles, and cultural shifts that threatened its Christian mission. The Grays’ four-decade journey reveals how faith, perseverance, and surrender to God’s purpose turned a crumbling facility into one of America’s premier pediatric hospitals. This inspiring account demonstrates that when ordinary people respond to God’s extraordinary call, miracles happen—not just once, but generation after generation.
