In the history recorded by Luke in the book of Acts, it seems Spiritual manifestations/miracles accompany the spread of the gospel throughout the Roman empire, but that they are more prominent in the early sections of the book of Acts than in the latter. A commentary I am reading quoted W. L. Knox, who wrote, "We have a steady reduction of the emphasis on the miraculous aspect of the working of the Spirit which corresponds to the development in the Pauline Epistles." (W. L. Knox, The Acts of the Apostles, Cambridge: University Press, 1948, p. 91) What are your thoughts on this? If this is so, why are the miracles/manifestations more prominent in the early part of the book of Acts that the latter part? Is there a corresponding element between this and Paul's claim that where there are prophecies they shall fail, where there are tongues they shall cease, etc. (I Cor. 13)? Does anyone have or have access to Knox's Acts of the Apostles? I'd like to understand better his finish of the statement "...which corresponds to the development in the Pauline Epistles." Thanks.
