The increasingly complex socio-economic developments have significantly influenced the spiritual lives of church members, including a decline in faithfulness in attending worship services and participating in church ministries. Work demands, economic limitations, and changing social dynamics have become major factors causing some congregants to reduce their involvement in the life of the church. These conditions require the church to develop contextual, holistic, and biblically grounded ministry strategies that address both the spiritual and social needs of the congregation. This study aims to analyze church ministry strategies for enhancing congregational faithfulness in worship amid socio-economic challenges at the GKSI Pasaman Mission Post. The research employed a descriptive qualitative approach using the library research method. Data were collected from theological books, scholarly journals, and other relevant literature, and were analyzed descriptively to obtain a comprehensive understanding of effective ministry strategies within the church context. The findings reveal three primary strategies that are relevant for implementation: strengthening congregational spirituality through Bible study, prayer, discipleship, family worship, and small groups; providing social and pastoral care through home visitation, counseling, compassionate ministries, and congregational empowerment; and fostering the spiritual growth of youth and Sunday School ministries through continuous faith formation and Christian character development from an early age. These three strategies complement one another in strengthening spiritual life, increasing social concern, and fostering congregational commitment to Christian fellowship. Therefore, holistic, contextual, and Scripture-centered ministry strategies are effective in enhancing congregational faithfulness in worship while strengthening church growth in the face of various socio-economic challenges.
