If it is his "secret will" then how can you state that the Nation of Israel is not a fulfillment of prophecy or part of the divine order planned by God from the foundation of the earth?
Has God revealed his "secret will" to you?
Secret will (aka decretive will) simply means something not specifically declared to us in the Bible. E.g., the Bible does not tell us that Ronald Reagan was to be the 40th president of the US, although we know now that it certainly was.
This is over and against His prescriptive will, that which is plainly given to us in the Bible. An example of that would be that the Christ should be born of a virgin, or that He would be born in Bethlehem, or that the temple would be destroyed and OT sacrifices ended once for all time.
The existence of modern Israel is not part of God’s prescriptive will since nothing in the Bible can be positively and definitely linked to modern Israel.
Has God revealed his "secret will" to you?
No, but that is irrelevant to the subject at hand as I have demonstrated.
