“It is indeed a song of steps. And as I have often said to you, these steps are not made to descend but to ascend. The questioner wishes then to ascend; and where does he wish to ascend if not to heaven? What does this mean—to ascend to heaven? Does he wish to ascend so as to be in the heavens with the sun, the moon, and the stars? Far from that! But there is in heaven an eternal Jerusalem where the angels, our co-citizens, are. From these co-citizens we on earth are estranged. In this exile we sigh; in the city we shall have joy.”
