Have you ever wondered what it felt like to be chosen by God as a special nation? Do you think you would feel humbled, or do you think you would more apt to be proud and feel superior than every other nation or people?
There were some Hebrews in both camps. But the reason God choose the descendants of Abraham to be a nation had nothing to do with their worthiness. Abraham's ancestors worshiped false God's. His family was from Haran. In fact some scholars, based on Genesis 11:31, believe God first called Abraham's father to go to Canaan, but he disobeyed and remained in Haran.
So God did not call Abraham because he was already holy. The point of choosing Abraham was to illustrate how turning to God and relying on him can bring you victory and peace.
God has called every believer to be part of a Holy Nation so that we are examples to others of what belonging to God means and the benefits of serving Him.
