This thesis discusses the contribution made by John Wimber to the theology of evangelism, discipleship and ministry. These contributions are contextually placed within a Reformed congregation that is part of a Confessional Presbyterian Denomination. While it does not address specifics with one congregation, the principles aim to be applicable to all such congregations. It seeks to challenge the accepted attitudes toward evangelism, the integration of new converts into the Church through discipleship, and the release of these converts into some form of ministry. This thesis argues for a re-evaluation of the power of the Holy Spirit in confirming the gospel with signs ccompanying, in filling each believer with his fullness and the giving of spiritual gifts, and a release of these gifts through every member ministry as a possible methodology to be implemented in Presbyterian congregations. This thesis aims to offer a middle way between pentecostalism and Cessationist theology through the ministry philosophy of John Wimber, himself an ordained minister of a Reformed denomination. It seeks to respect the theological and historical traditions of Presbyterianism, while not being uncritical of some of its current methodologies. It also seeks to suggest that the theology of the Reformed faith is best suited to a Charismatic methodology with the emphasis on God’s sovereignty, omnipotence and sacramental theology. It seeks to place the practice of evangelism, discipleship and ministry within the context of a local congregation as that which is best suited to minister to the needs of that local community in which it is planted, and to evangelise, disciple and train those members to meet the spiritual needs of that community. This thesis argues for an integration of the presence and power of the Holy Spirit in the context of a Bible and preachingbased congregation.
