What will happen to Israel in relation to the root of Abraham?
Israel will be set back on the root of Abraham. From that restored position, Israel will go into the Kingdom of God. The context repeats that Israel is going to enter the Kingdom of God, emphasizing this outcome. Thus, the future described centers on Israel's restoration to Abraham's root and entrance into God's Kingdom.
Les explains that He will set Israel back on that root of Abraham. The result is that Israel is going to go into the Kingdom of God. The transcript repeats this point several times: Israel is going to go into the Kingdom of God. So the promise ties Israel's restoration to the Abrahamic root directly to Israel's entrance into God's Kingdom.
