[Acts 2] forms something of a parallel, in Acts, to the baptism of Jesus in the gospel, and thus demands to be understood not simply as a fascinating and initiatory incident in the very early life of the church but as the story which must be held in the mind as a kind of running heading for all that is to follow. Just as Jesus’ baptism and anointing with the Spirit in Luke 3 is to be understood as standing behind and explaining everything else, from His “Messianic” proclamation in Luke 4 to His messianic death and resurrection, so that coming of the Spirit in Acts 2 is to be understood as standing behind and explaining everything else that the church then does, particularly its worship, its mission and its bold stand in obeying God rather than human authorities. Thus, when Luke later tells us that the Christians gathered together were all filled with the Spirit and spoke God’s word with boldness, this should be understood not as a fresh and momentary filling, repeating Pentecost as it were on a strictly temporary basis, but as a fresh manifestation of what had been the case all along since Pentecost itself. The church from Acts 2 onwards is the Spirit-led church, with worship as a integral part of its proper life.
