"Having gifts that differ according to the grace given to us, let us use them: if prophecy, in proportion to our faith; if service, in our serving; the one who teaches, in his teaching;". ESV [My emphasis].
"...being high priest that year he prophesied that Jesus would die for the nation".
The high priest prophesied about Jesus. Does "prophecy" in Romans 12:6 have to be direct reference to Jesus? [ What about correct predictions re: football matches?]
"Do not think that I have come to abolish the Law or the Prophets; I have not come to abolish them but to fulfill them."
Jesus' coming fulfills "them". Does that include prophecy which occurs after His coming? What is the point of New Testament Romans "prophecy" if not to predict His coming?
[For some, I gather, prophecy is of interest in that Ruth Graham wrote this in The New York Times: "Prophecy is a facet of the fast-growing charismatic Christian movement, which has an estimated half-billion followers worldwide and is characterised in part by the belief that the "gifts of the spirit"... continue into the present day rather than being an artifact of Biblical times".
