With regards to Amil, I've been thinking about how a spiritually minded OT Jew would have viewed prophecies like Isaiah 65-66, Ezekiel's Temple, etc. Is there any sound principle of interpretation they might have used to realize that the kingdom was spiritual but being spoken of in earthly and Jewish-centered terms? Or was there no way for them to know that until Christ came and revealed that? There seems to have been some way for them to have known (and I have a hunch how) based on what Hebrews tells us about Abraham.
Read Michael Brown's stuff on Jewish apologetics. He notes how pious Jews wrestled with Ezekiel's temple. It's not simply a difficulty of "sacrifices still going on." There are a number of difficulties in taking it literally (for example, it doesn't mention a ceiling).
