From Chapter VIII of Herman Melville's Moby Dick

...for the pulpit is ever this earth's foremost part; all the rest comes in its rear; the pulpit leads the world. From thence it is the storm of God's quick wrath is first descried, and the bow must bear the earliest brunt. From thence it is the God of breezes fair or foul is first invoked for favorable winds. Yes, the world's a ship on its passage out, and not a voyage complete; and the pulpit is its prow.
