How long will Israel's spiritual blindness last according to Romans 11:25?
Israel's spiritual blindness will remain on the nation until the fullness of the Gentiles is brought in. The fullness of the Gentiles is the Body of Christ; when that Body is full, God will take it out of the way and begin dealing again with Israel.
Les explains that Paul says Gentiles are to understand this spiritual blindness has fallen on the nation of Israel, and it will remain on their spiritual eyes until the fullness of the Gentiles is brought in. The fullness of the Gentiles is the Body, the Body of Christ. So when the Body of Christ is full, God will take us out of the way, and He will start dealing again with the nation of Israel. Les connects this to the Tribulation being primarily Jewish and points back to Jeremiah 30.
For I would not, brethren, that ye should be ignorant of this mystery, lest ye should be wise in your own conceits; that blindness in part is happened to Israel, until the fulness of the Gentiles be come in.
