The study aims at establishing the relationship between servant leadership and growth of the evangelical churches in Kenya. Social Identity theory and MCGavran’s church theory were used to advance a theoretical foundation of the study. This study adopts cross sectional survey design. The study was undertaken among the 179 churches registered with the Evangelical Alliance of Kenya. A Stratified random sampling technique was considered to settle for a sample size of 124 churches using the Slovin’s formula. The study has used both primary and secondary data. Quantitative data from the closed ended questions was analyzed using SPSS version 24 and qualitative data from the open-ended questions were analyzed using NVivo version 12. Descriptive statistics such as percentages, frequencies, mean and standard deviation were used for the quantitative data. The outcome of the study showed that the F-Calculated (1, 102) = 212.662 which is greater than F-Critical (1, 102) = 3.934 at 5% significant level (2-tailed test) and p-Value = 0.000 < 0.05. An indication that servant leadership significantly influence growth of evangelical churches. When the independent variable (servant leadership) is held constant, growth of evangelical churches is at 0.258. At the same time, an increase in servant leadership by one unit would lead to an in growth of evangelical churches by 0.925 units with a p-Value of 0.000<0.05. Further, a positive beta coefficient explained that the relationship was positive implying that when servant leadership is embraced by leaders of evangelical churches, growth of such churches in terms of the number of local churches, number of members, number of pastors/ministers, number of supportive staff, as well as the revenue will also increase.
