Some of the balancing between what is literal and allegorical can indeed be difficult to make. But I believe such a distinction is absolutely necessary. To cut it very short: what it basically boils down to is if the bulk of major prophecies have been fulfilled and had their yea and amen in the person and work of Christ or not. Here only positive or negative will do. It is particularly on this one issue that a- or postmillenials differs from the premillenials. Not all interpretations are plausible. The risk of adopting a strictly literal interpretation of scripture means an open door for arbitrarily dissecting what "every detail" actually is and if it has been fulfilled or not. There are many messianic prophecies that some people are making a big issue out of having not been literally fulfilled or fulfilled in "every detail". They use this as an argument that Jesus was not the Messiah. Mined land.
PS. Good to see that amillenials are in majority.
