You wrote: “When Israel failed to recognize Jesus as their Messiah on the first Palm Sunday, He said that knowledge of Him would henceforth be hidden from their eyes. Zechariah 12:10 is a prophecy that tells us when their spiritual blindness will be lifted.”
Also, 2 Thessalonians 2:11-12, Paul writes: “For this reason God sends them a powerful delusion so that they will believe the lie and so that all will be condemned who have not believed the truth but have delighted in wickedness.”
Of course, this is a reference to the Anti-Christ and the delusion that will come over people so they believe in “him” instead of God. My question is, are these delusions “predictive” or “prescriptive?” Are these prophecies simply telling us what “will” be or did/will God actually “prescribe” them or make it/them happen?
In Romans 11:7-10 Paul seems to say that the spiritual blindness Israel has experienced was a direct consequence of their failure to recognize Jesus as their Messiah. I believe Paul was confirming the Lord’s statement to that effect in Luke 19:41-44 when He said, “Now it is hidden from your eyes.”
I also believe the same will be true of those who refuse to believe the truth about Jesus in the end times. 2 Thes. 2:11-12 says God will send them a strong delusion so they will believe the lie.
It appears that both the blinding and the delusion are deliberate acts of God in response to the actions of people. It’s as He is saying, “You refuse to accept my Son? Fine. I’ll make it so you can’t accept Him.”
