I think Roy explained it pretty well. Obviously God DOES choose some people or groups of people over others for His purpose. And in his Sovereignty He makes some beautiful, some less-than-beautiful, some highly intelligent, some less so...etc. etc. That doesn't mean He chooses them BECAUSE they are beautiful, intelligent, etc. He made them according to His purpose in the first place.
Niether the Elect or the Jews are special in any other way than that God chose them. He didn't choose them because they are special. He is no repecter of 'persons'.
I could go on, but I'll stop. I wish I was more organized to point you to where Ray discusses this in depth, but I can't even remember whether it was in an article, and email, an audio or audio transcript.
