When will Israel's spiritual blindness come to an end?
Israel’s spiritual blindness will end when the fullness of the Gentiles has come in—that is, when the body of Christ is complete, the last person is saved, and the church is removed at the rapture. At that point God will resume His dealings with Israel, and they will again enter a spiritual relationship with Jehovah.
Les explains that Israel’s spiritual blindness was a secret hidden in God’s mind: while God would spend 1900 and some years calling out the Gentiles, Israel would be in spiritual blindness. This blindness is “in part”—not forever, but for a segment of time—and it lasts “until” the fullness of the Gentiles has been brought in. The fullness of the Gentiles is the body of Christ. When the body of Christ is finally filled, the last person is saved, and the church is removed at the rapture, then He will pick up where He left off with Israel, the Jew. That is when their spiritual blindness will more or less come to an end, and they will begin to have again a spiritual relationship with their Jehovah God. Les notes Jesus also refers to three “untils”; in Matthew 23, Israel would not see Him, He would be moved from their midst, and He would go back to glory.
