God spoke through Isaiah:

chapter 6:9 And he said, Go, and tell this people, Hear ye indeed, but understand not; and see ye indeed, but perceive not.10 Make the heart of this people fat, and make their ears heavy, and shut their eyes; lest they see with their eyes, and hear with their ears, and understand with their heart, and convert, and be healed.

This became a recurring theme throughout the Bible; paraphrased by other OT prophets and NT Apostles. A lot has been said about this topic, but I'm hoping for a rethink and review of our understanding of our understanding of the passage.

My question therefore is, has this blindness of heart been removed from Israel or not? If you believe it has, what is your scriptural evidence? The same goes for those who believe it is not yet removed.
