At the time of the evening sacrifice, the prophet Elijah went over to the altar and prayed: “Lord, God of Abraham, Isaac, and Israel, demonstrate today that you are God in Israel, that I am your servant, and that everything I have done has been at your command.
Then he said, “I am the God of your father, the God of Abraham, the God of Isaac, and the God of Jacob.” Moses covered his face, because he was afraid to look at God.
The God of Abraham, Isaac, and Jacob—the God of our forefathers—has glorified his servant Jesus. He was the one you betrayed and rejected in the presence of Pilate, even after Pilate had decided to release him.
But they're looking for a better country instead, a heavenly country. That is why God isn't disappointed with them, and is happy to be called their God, for he has built a city for them.
