Disciples Devoted to Fellowship: The One Another Principle is a 13-lesson workbook designed to reconnect modern Christians with the deep, heartfelt unity observed in the early church. It challenges American Christianity's often peripheral approach to faith, with spiritual life frequently demoted to a subsection due to our busy, distracted lifestyles. Drawing inspiration from the first Christians for whom Christianity was life-encompassing, this workbook emphasizes the importance of yearning for fellowship and cultivating a servant's heart. Amidst cultural pressures and superficial connections, it serves as a guide to restoring genuine, intimate relationships within the spiritual family. The goal is to encourage readers to prioritize their spiritual pursuits, reaffirm their commitment, and reinvent their daily lives around Christianity, thereby echoing the devotion of early disciples.
