So there is Divine prophecy outside of Christ?
No, silly, the Heavens and the Earth are His. The events prophesied to Jews are for Jews and Jesus incarnated as a Jews, so any prophecy regarding Jerusalem of the Jews is His. The Old Testament is full of prophecies which at first appear to not be in regards to Jesus. That’s precisely why the Bereans were affirmed by Paul, for searching the scriptures daily to check the data. You cannot have a God authored prophecy without it in some way regarding Jesus for He was in the Beginning with God and was God, and without Him was nothing made.
