A Lasting Promise™ is a book that differentiates itself from other books on marriage in that it combines lessons from Scripture, general biblical principles, and historic Christian teachings with a strong foundation of university-based research about what leads to marital success. Unlike many books that are theoretical or insight oriented, A Lasting Promise™ is designed for action by including the practical strategies from the internationally recognized PREP™ program. The combination of inspiration from Scripture and proven strategies of PREP will fill couples with the motivation and skills necessary to get up and do what they need to do to keep their marriage strong and happy.
