No, it's not. It's often characterized that way, but with respect, you didn't read it at all. You couldn't have.
The gist of the link is as I summed up earlier:
" One strand of thought goes that the physical blessings promised by God to Abraham, and passed to his descendents via the birthright, are based upon bloodline whether or not the people of the bloodline know it. This isn't an indicator or barometer of how spiritually good or moral those descendents are. They could be the scum of the earth, but God made the promise and so he will keep that promise.
BUT, and it's a big but, this has nothing to do with salvation or redemption under Christ. As you pointed out, Christ died for all. Black, white, yellow or green. Gentiles become heirs to the "better" promise.
Heb 8:6 But now hath he obtained a more excellent ministry, by how much also he is the mediator of a better covenant, which was established upon better promises.
These promises include the promise of eternal life through the new covenant, mediated by Christ. There is no partiality. Not just native born Israelites, physical Israelites, can take hold of this. And just being a native Israelite doesn't automatically give you the promise of eternal life. All have to come to the promise through Christ. "
I don't believe that the seemingly never-ending conflicts within that “Triangle” are due to anyone's MIS- interpretations of the Abrahamic territorial promises (excepting the false positions of Islam on the matter). I believe the conflicts are there precisely because that is where the territorial promises (as well as other promises made to Israel as a nation) will be fulfilled, and Satan and all of his hordes are involved in a spiritual warfare over that place.
