Is the nation of Israel currently blinded spiritually?
The nation of Israel is indeed blinded spiritually, having been in that condition for roughly 1900 years. However, Scripture declares God is not finished with His covenant people, as Romans 11 emphasizes. This blindness is temporary and does not negate God's ongoing covenant purposes.
Les explains that while Israel has been in spiritual blindness for the last 1900 some years, and the nation as such is blinded, Romans 11 trumpets that God is not through with His covenant people. Les points out that from Genesis 12 through much of Acts, God dealt predominantly with Jews, with exceptions like Jonah, Naaman, Rahab, and Ruth. After Paul's call to the Gentiles, he went first to the Jews, then turned to Gentiles when rejected.
