This coming Sunday (June 12, 2011) is Pentecost Sunday on the Christian calendar. As part of my continuing series of sermons on “The Forgotten Member of the Trinity,” I will be preaching a sermon from Acts 2 titled “The Coming of the Spirit of Christ.” In my preparation, I was reading from Sinclair Ferguson‘s great contribution to IVP’s “Contours of Christian Theology” series. Here is what Ferguson said about Pentecost:
Pentecost publicly marks the transition from the old to the new covenant, and signifies the commencement of the ‘now’ of the day of salvation (2 Cor. 6:2). It is the threshold of the last days, and inaugurates the new era in which the eschatalogical life of the future invades the present evil age in a proleptic manner. Thus, from the New Testament’s standpoint, the ‘fulfilment [or “end”, ta telē] of the ages has dawned’ (lit.) on those who, through the gift of the Spirit, are ‘in Christ’ (1 Cor. 10:11). That which is ‘new’ in the new covenant ministry of the Spirit is therefore inextricably related to the significance of the Pentecost event.
