What happens when the Body of Christ is full?

When the Body of Christ is full, God will take the Body out of the way and will begin dealing again with the nation of Israel. The fullness of the Gentiles is the Body, and Israel's spiritual blindness remains until that fullness is brought in.

Les explains that the fullness of the Gentiles is the Body of Christ. Once 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. This connects to Israel's spiritual blindness, which remains on their spiritual eyes until the fullness of the Gentiles is brought in. Les then goes back to Jeremiah 30 to show that the Tribulation is primarily Jewish, pointing to travail and paleness.

Romans 11:25

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.

What happens when God finishes drawing the last person into the Body of Christ?

When God has finished drawing the last person into the Body of Christ, the fullness of the Gentiles is complete. Believers are out of here—delivered like a baby when the womb has formed every part—and then God can pick up and finish where He left off with Israel.
