To be a respecter of persons implies that one is unjust. It is impossible for the Lord to be unjust. He is holy and perfect in all His ways.

The concept of ChosenPeople is perverse. Abraham believed the Lord and the Lord rewarded His faith with a promise that His seed would be blessed. And that one particular seed would bless all the nations of the earth. That seed is Christ Jesus.

Hebrews are blessed as long as they operate in faith, just as gentiles.
