J. N. Darby · God's sovereignty proved in Abraham's family

In the first place, this truth displayed itself in the bosom of Abraham's own family. The Jews alleged their exclusive right to the promises in virtue of their descent from him, and to have their promises by right, and exclusively, because they were descended from him. But they are not all Israel which are of Israel. Neither because they were of the seed of Abraham were they therefore all children. For in that case Ishmael must have been received; and the Jews would by no means hear of that. God then was sovereign. But it might be alleged that Hagar was a slave. But Esau's case excluded even this saving thought. The same mother bore both sons of one father, and God had chosen Jacob and rejected Esau. It was thus on the principle of sovereignty and election, that God had decided that the seed should be called in the family of Isaac. And before Esau and Jacob were born, God declared that the elder should serve the younger. The Jews must then admit God's sovereignty on this point.
