Interpersonal Relationship as a Missional Ministry to the Affluent

This study examines interpersonal relationships as a missional approach for engaging with the affluent. The Great Commission in the book of Matthew 28:18-20 states that Christ commissioned His disciples to reach all nations with the gospel message and to make disciples of all peoples. Without an appropriate model for ministering to this wealthy, gospel ministers risk focusing only on poor and marginalised communities, thus failing to fulfil the Great Commission's inclusive call. The study used a qualitative approach to analyse primary data from Luke 19:1-10 and theological commentaries. It also employed a library-based method to examine relevant secondary sources. The study analysed interpersonal communication theories, including Uncertainty Reduction Theory, Attachment Theory, and Interpersonal Needs Theory. Using the interaction between Jesus and Zacchaeus in Luke 19:1-10 as a case study, the research demonstrated how Jesus used interpersonal relationships to minister to Zacchaeus. The findings suggest that loneliness and a desire for privacy are barriers to ministry among the wealthy. At the same time, genuine connection, empathy, and pastoral presence are essential remedies; the affluent desire to feel valued and to belong through authentic relationships, not just financial transactions. The study concludes that Zacchaeus's change of heart resulted from genuine relational ministry, emphasising that interpersonal relationships are crucial when ministering to the wealthy. This research contributes to the field of missiology by addressing the often-overlooked affluent population as a potential mission field. It also provides gospel ministers with practical models of ministry to the wealthy through authentic interpersonal relationships rather than transactional approaches.
