This quote on the Bible is from the great 20th century theologian and rabbi, Abraham Joshua Heschel:
The divine quality of the Bible is not on display, it is not apparent to an inane, fatuous mind; just as the divine in the universe is not obvious to the debaucher. When we turn to the Bible with an empty spirit, moved by intellectual vanity, striving to show our superiority to the text; or as barren souls who go sight-seeing to the words of the prophets, we discover the shells but miss the core....To sense the presence of God in the Bible, one must learn to be present to God in the Bible. Presence is not a concept, but a situation.... Presence is not disclosed to those who are unattracted and try to judge, to those who have no power to go beyond the values they cherish; to those who sense the story, not the pathos; the idea, not the realness of God.
The Bible is the frontier of the spirit where we must move and live in order to discover and to explore. IT is open to him who gives himself to it, who lives with it intimately. We can only sense the presence by being responsive to it. We must learn to respond before we may hear; must learn to fulfill before we may know. It is the Bible that enable us to know the Bible.
