3INTRODUCTION,The biblical words for Spirit(ruachin Hebrew. pneumain Greek) signify breath, and the blowing of the wind. The Spirit focuses attention, not on himself, but on the Savior1. A spirit might also mean a spectre or a ghost2.Many Christians had no difficult in accepting the full divinity of the son but found themselves unable to extend that confession to the Holy Spirit.3He has a ministry of illumination through the Word that convinces us of the reality of Christ; a ministry that leads us to see our need of Christ so that we embrace him in faith and love; a ministry that keeps us prayerfully in touch with Christ and assured of salvation by Christ; and a ministry of oneness which connects us to Christ in such a way that his risen life flows into us andhe ministers to others through us. The first act of the risen lord was to breathe the spirit on the disciples and send them forth into mission.4The work of the Holy Spirit is a vital necessity in the experienced event of personal conviction and conversion. Conversion is a much-misunderstood subject. The Holy Spirit, according to Calvin, could be seen working in several aspects of the believer, especially in salvation5. There are three issues regarding conversion that I will attempt to clarify: (a) the Spirit as the author of conversion; (b) the work accomplished by the Spirit in conversion; and (c) the means used by the Spirit in conversion.1English Standard Version (ESV)2Module Charles Francis Digby, The Holy Spirit, Grand Rapids, W.B.
