And I actually have 39 books of the Old Testament that clearly and specifically state that the promises to physical Israel still stand (Jeremiah 33 is a good chapter to start with). You're taking it much too far to one extreme. Romans 11 - we are grafted into THEIR tree - don't boast against the branches. They are currently blind for OUR sake. One day their eyes will be opened.
To argue that those blessings belong to an atheistic hegemonistic, secular state which will expel those who preach the good news of the Messiah, is only further testimony that modern American Christians don't know 1)the bible and 2)the history of theology of end times
Again, don't boast against the branches - how long ago were you and I in such an ungodly state but by His grace were saved?
And I would argue that you might not know your Old Testament and how it relates to the New Covenant. That secular state is in place because God promised that it would be, and the Jews are currently being regathered in unbelief, as prophesied in various places - Ez 37 comes to mind. God promised to "save the tents of Judah first" - Zech 12 - happening now. God will bring them through the fire and then pour out His Spirit upon them - again, Zechariah. Just a couple of references among dozens upon dozens.
The whole story is one seamless flowing tale of undeserved love and redemption. The nation of Israel was chosen of God to be His catalyst through whom One would bring salvation to all. It starts with them and ends with them. One chosen people, to whom WE are added. Don't misunderstand me - they need Messiah too. But God's not done with them, not by far.
Correction - my mention of Jer 33 should actually be Jer 31...although chapter 33 is pretty specific as well. :)
Excellent response.
