"You only have I chosen of all the families of the earth. Therefore I will punish you for all of your sins."
It is amazing how this ancient delusion of Israel persists even today in millions of people who think they are "saved by faith alone."  God's election, God's grace, God's covenant with his people has from the beginning, continually, and always rested upon the contingency that the recipients of his mercy would continue to love God, and to the best of their ability, obey him.
