The purpose of this study was to identify vital leadership competencies needed by church leaders for church growth as well as explore other contributing factors to phenomenal church growth. The goal of this qualitative study, using a modified Delphi design, was to explore the insights and experiences of 10 senior pastors from 100 of the fastest growing churches in the United States. Data collected in this study were gathered in three subsequent rounds that included two internet-based surveys and a 30- to 45-minute in-person interview session. The data from this study indicate there is a critical role for churches in the United States to play in the coming decades despite current trends toward membership decline. Church leaders hoping to grow their churches must realize and understand the necessity of connecting with the surrounding culture via the relevancy of meeting needs and the empowerment of their congregations while using leadership characteristics displayed by Jesus Christ to maximize ministry in the current era.
