What is the fullness of the Gentiles in Romans 11:25?
The fullness of the Gentiles is the Body of Christ, completed when that Body is full. Paul explains that Israel's spiritual blindness remains until this fullness is brought in. Then God will take the Body out of the way, begin dealing again with Israel, and the primarily Jewish Tribulation will follow.
Les explains that Paul is telling Gentiles to understand that spiritual blindness has fallen on the nation of Israel and 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. When the Body of Christ is full, God will take it out of the way and start dealing again with the nation of Israel. Les then connects this to the Tribulation being primarily Jewish and points to Jeremiah 30, where a man is seen with his hands on his loins like a woman in travail and all faces are turned to paleness.
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.
