Abstract

The church has the responsibility to fulfill the Great Commission through evangelistic ministry that is responsive to the needs of society. However, the implementation of evangelistic mission faces various challenges that require churches to develop contextual ministry strategies while actively involving the entire congregation. This study aims to describe the role of GEKI MRC Medan Marelan Church in carrying out its evangelistic mission and to identify the forms of ministry that support the implementation of this mission. The study employed a descriptive qualitative approach using interviews, observations, and documentation as data collection techniques. The research participants consisted of church members, cell group leaders, and church ministry leaders. The findings reveal that GEKI MRC Medan Marelan Church plays an active role in conducting various evangelistic activities, including seminars, Bible study, social outreach, pastoral home visits, and community-based programs involving local residents. These activities encourage congregational participation in ministry while expanding the reach of the Gospel through relational and contextual approaches. The findings also indicate that the active involvement of church members strengthens the relationship between the church and the community and enhances the effectiveness of evangelistic ministry. The study implies that churches should continue to develop innovative, participatory, and adaptive evangelistic strategies in response to social changes so that evangelistic ministry remains relevant and generates a positive impact on both the congregation and the wider community.

Abstract

Character building of children is one of the main objectives of Sunday School ministry which is greatly influenced by teacher competence in implementing the learning process. Sunday School teachers are required to have pedagogical, personality, social, and professional competence in order to be able to instill Christian values ​​​​effectively to children. This study aims to analyze the influence of Sunday School teacher competence on the character building of children at the Elim Christian Church of Indonesia (GEKI) MRC Marelan. The study used a quantitative approach with a survey design and a positivistic paradigm. Data were collected by distributing questionnaires to respondents consisting of parents and children who actively attend Sunday School at GEKI MRC Marelan. Data were analyzed using descriptive and inferential statistics, including the Shapiro-Wilk normality test, correlation analysis, and coefficient of determination. The results showed that Sunday School teacher competence had a positive and significant effect on the formation of children's character with a correlation value (R) of 0.609 and a coefficient of determination (R²) of 0.370. These findings indicate that teacher competence contributes 37% to children's character formation, while the remaining 63% is influenced by factors outside the research model. This study concludes that improving Sunday School teacher competence through training, coaching, and professional development is a strategic step to increase the effectiveness of Christian education services and support the formation of children's character in accordance with biblical values.
