Has Israel attained the fullness God has in store for them?
No, Israel has not attained the fullness God has in store for them. Their diminishing brought riches to the Gentiles, but their fullness has never been attained. It is still coming. Israel today, like in Samuel's time, seeks to be accepted by the Gentile world rather than remaining distinct.
Les explains that the fall and diminishing of Israel brought riches to the world and to the Gentiles. He asks how much more their fullness will be, then states they have never attained it yet; they have never attained the fullness God has in store for them, but it is coming. He warns not to sell the Jew down the river, because they will go through horrible times. He observes that the little nation of Israel is being backed into a corner and frantically trying to make peace. Les compares Israel today to Israel at the time of Samuel, when they wanted a king and to be like the nations around them rather than different. He concludes that Israel today is no different, with its government frantically seeking to be accepted by the Gentile world.
