Are the Jews still blinded to the fact that the Law has been abolished and replaced by grace?

Yes. Israel remains blinded to the truth that the whole system of Law has passed off the scene, is abolished, and has been replaced by the tremendous revelation of the mysteries—the grace of God. This blindness continues to this day, so they cannot see the end of that abolished system.

Les explains that when Moses put the veil over his face, it was not merely because Israel could not stand the brightness of his complexion. Rather, they could not see the end of the whole system of Law. That blindness continues to this day. Israel is blinded to the fact that the Law has passed off the scene, is abolished, and in its place is the tremendous revelation of the mysteries—the grace of God. Grace is not a license to sin, but believers live differently because they have new desires, not because they are under Law.

2 Corinthians 3:13

And not as Moses, which put a vail over his face, that the children of Israel could not stedfastly look to the end of that which is abolished:

Why are the children of Israel still blinded to the end of the Law?

The children of Israel are still blinded because Moses' veil pictured their inability to see the end of the Law. That entire system has passed off the scene, abolished and replaced by the revelation of the mysteries—the grace of God. They remain unable to steadfastly look to its termination.
