It is profound; all other sciences are but shadows; this is a boundless, bottomless ocean; no creature has a line long enough to fathom its depths; there is height, length, depth, and breadth ascribed to it, yea it passes knowledge. Eternity itself cannot fully unfold Him. It is like exploring a newly discovered land; by degrees you search further and further into the heart of the country. Ah, the best of us are yet on the borders of this vast continent! The study of Jesus Christ is the noblest subject that ever a soul spent itself upon.
—John Flavel (1627-1691)
