Wow already finished with 5 chapters of Isaiah. Here’s a thought. Jesus told all assembled in Luke 4 the portions of Isaiah 61:1-2b were fulfilled in their presence. Are we to conclude the remainder of the prophecy stretching for four chapters will be. Unfulfilled or dismiss it. The first 1.5 verses of the prophecy were literally fulfilled as announced by Christ Jesus.
If you want to point to a particular verse(s) in Isaiah that you feel make your point, please do so. I am not seeing a literal 1,000 year reign in Isaiah, Matthew, Peter, Corinthians or Revelation.
btw, under the literal historic method of interpretation, wouldn’t a day be a day and 1,000 years a 1,000 years?
