Hi and I am just answering what you post !!
Yes there was a Kingdom in the North and there was a Southern Kingdom and one day they will be one stick OR one Kingdom again as Heb 8:8 prove my point as the New Covenant will unite the House of Judah and the House of Israel in the New Covenant !!
This has NOTHING to do with Ron 11:17 as we are the Body of Christ and not Branches !!
If you bring it up I will answer!!
The opening post has to do , why Israel has been set aside , and have you adresses that , like Luke 13:13:6-9 ??
Romans 11 has everything to do with the body of Christ. The body is Israel. Israel is the body. The Gentiles of Romans 11 are grafted into the Body. There is only one body. Israel was already mostly set asside with the captivity in Assyria. The only people left was Judah but as Romans 11 says there is still a remnant. That Remnant and the believing Gentiles are grafted together into the one body. The Gentiles being grafted in are the old northern kingdom and foreign gentiles also. Judah is now set aside also unless they are believers and then they are in the body. All the Jews set aside during Romans were in a stupor except the remnant.
