Abstract: For several decades, the rate of backsliding of church members in West Congo Field (WCF) has been glaring and ever increasing, despite the use of various strategies to close the back door. Having discovered, in a previous study, the factors associated with backsliding in the said mission Field, the present study targeted small group ministry for discipleship as a strategy to reduce the rate of backsliding and reclaim backsliders. It is true that there is a lot of literature on small group ministry and that it has been used in WCF, but the bottom line is that they have not done enough to address the high rate of backsliding and reclaiming backsliders. The researcher used the methodology of program development. The implementation of this strategy, which consisted of the creation of new small groups and the revitalization of existing ones resulted in a significant reduction of backsliding rate of around 33 %, an increase in the church growth rate of up to 11 percent, and also in the backsliders’ claim of the order of 17%. The findings of this study are crucial for the Seventh-day Adventist church in WCF because they have shown the improvement of member retention, effectively nurturing of new converts, the growth, and the stability of the church in this Field. So, researcher recommends that WCFpromotes the creation of small groups in all local churches in its territory and revitalize those that are not operational.
