This article examines the influence of cell group (komsel) leadership, Christian lifestyle, and discipleship on the growth of the congregation at Christian Ministry Church (CMC) Jakarta. Employing a quantitative correlational design with 140 respondents, the study operationalizes three independent variables (X₁ = cell leadership; X₂ = lifestyle; X₃ = discipleship) against the dependent variable (Y = congregational growth). Pearson correlation analysis reveals significant correlations between cell leadership and lifestyle (r = .800, p < .01) and between cell leadership and discipleship (r = .591, p < .01), whereas direct correlations with Y were non-significant individually. Multiple regression yielded R = .752 and R² = .566, indicating that collectively the three predictors account for 56.6% of variance in congregational growth. These findings reinforce the argument that organic church growth is multidimensional and that the synergistic interaction of cell leadership, moral integrity, and discipleship constitutes a coherent growth ecosystem. Theological and pastoral implications are discussed within frameworks of contemporary missiology and cell ecclesiology.
