The Bible is quite clear, and there is no ambiguity that the Holy Spirit is still active in our world. The book of Acts, which sometimes goes by the longer title of “The Acts of the Apostles,” could just as accurately be called “The Acts of the Holy Spirit through the Apostles.” After the apostolic age, there have been some changes—the Spirit does not inspire further Scripture, for example—but He continues to do His work in the world.
