Quick answer

God commands an expanse to separate the waters, beginning to shape habitable space. He continues bringing structure to the formless deep.

Overview

On the second day God speaks an 'expanse' (the sky or firmament) into being to divide the waters above from those below. This act of separation, like the dividing of light from darkness, shows God making the world orderly and prepared for life. The passage reflects an ancient picture of the cosmos while teaching the enduring truth that God alone structures and governs the heavens and the earth.
