Israel is the offspring of Abraham, Isaac, and Jacob. This not only applies to those who have the genetic trace, but to all who have entered into that identity whether by intermarriage, proselytization, or other means. Isn’t it worthy of note how God identified Himself at the burning bush? “I am the God of your father-the God of Abraham, the God of Isaac, and the God of Jacob.” He didn’t identify Himself with Abraham Lincoln, Ishmael, or Mahatma Gandhi. Abraham, Isaac, and Jacob, are the fathers of Israel, a people who are with us to this day. That counts for something.
Does it mean that the rest of the world is washed out? It was through Israel that the promise of hope was given and established. “In your seed all the nations of the earth shall be blessed.”
