Dr. John H. Roller has been an entrepreneur primarily in the field of church planting.  He wrote 2 books relating to his experience, The Doctrine of Immortality in the Early Church and Advent Christian Church Planting Efforts 1950-1980.  These books were combined, with additional material, as Immortality for Entrepreneurs to address misconceptions of too many entrepreneurs that success can be assumed.  Success can only be achieved through knowing the Truth.
