Who are the Blessed?

Ref: Romans 4:6-16

In Romans 4:6-16 we read about the blessings delivered upon Abraham and his descendants. As I read this in church, I had the following thought:

If Abraham is the Father of Israel, and Israel the nation of Jews, and his people are blessed as righteous, and Abraham was blessed when he was still uncircumcised, then we know that you need not be Christian to be blessed.

So then it would be possible for a Jew or Muslim or Buddhist, for example, to be blessed through faith and living the life prescribed by Jesus in his teachings, without believing that Christ has come.
