Many Jewish sects believe there is. The same with many Christians.
How do you "prove" that a time of God is upon us or is around the corner? Aside from direct revelation, all we have is the possibility of certain scriptures aligning.
The Apostles weren't aware of the resurrection until after it had occurred, even though Jesus told them many times.
At the same time, I, too, would counsel caution. I would also counsel knowledge of other perspectives. I am a sola scriptura kind of guy.
The bottom line is this: if we don't appeal to scripture as authoritative then to what do we appeal?
The olive tree is the place of privilege that was first occupied by the natural branches (the Jews). The wild branches are Gentiles who, because of the unbelief of Israel, now occupy the place of privilege. The root of the tree is the Abrahamic covenant that promised blessing to both Jew and Gentile through Christ. (Ryrie Study Bible)Another odd thing about Ryrie’s quote. It seems to make no allowance for Jews today (and for the past 2000 years) who come to faith in Christ. Note the structure of his comment. Place of privilege WAS occupied by Jews, and NOW is occupied by gentiles. No hint of Jews and gentiles together today as one new man ala Ephesians 2. IOW, no mention of the Church!
Again, this is a problem with classic dispensationalism. The proponents are often reluctant to see the implications of their system.
