Genesis 1

Verses 6–8 WEB Voices

After light, God continues the week by making an expanse in the middle of the waters. Verses 6–8 are day two: sky-space named Heaven, waters above and below distinguished, evening and morning. The Creator is not only originator but arranger—making room in which later life will live and move.

Genesis 1:6

6God said, “Let there be an expanse in the middle of the waters, and let it divide the waters from the waters.”

Arminian

God said, “Let there be an expanse in the middle of the waters,” to separate waters from waters. Day two continues creation by speech: space is opened, not discovered.

God makes room. The expanse is hospitality in cosmic form—a place where birds will later fly and rain will later fall, all by the same generous word.

Reformed

The second day’s word commands an expanse to divide waters from waters. Distinction again comes by decree, not by the waters’ own sorting.

The Creator structures the cosmos as He wills. Heaven and the deep do not negotiate; they are placed. Government of the world is as original as its existence.

Genesis 1:7

7God made the expanse, and divided the waters which were under the expanse from the waters which were above the expanse; and it was so.

Arminian

God made the expanse, and divided waters under it from waters above it—“and it was so.” Word and deed agree; the world answers Him.

Classical Arminians gladly confess that creation obeys. “It was so” is not fate crushing nature; it is the fitting response of what God makes to the God who speaks in truth.

Reformed

God made and separated, and it was so. The clause closes the gap between command and fulfillment.

God’s word in nature does not return empty. Waters above and below take their stations because He made the expanse; whatever secondary processes we later describe remain servants of that word.

Genesis 1:8

8God called the expanse “sky”. There was evening and there was morning, a second day.

Arminian

God called the expanse Heaven; evening and morning mark the second day. Naming again: the sky is His, not a canopy of competing deities.

The week moves by God’s naming and timing. Heaven as gift-space invites later praise, not anxiety that the sky might collapse without our management.

Reformed

He names the expanse Heaven and completes the second day. Title and time belong to the Maker.

To call it Heaven is to claim it. The visible sky is creature, not god; its order is the Lord’s ongoing work, as sure as the day He first named it.

Arminian Notable voices

“Let there be a firmament—An expansion; so the Hebrew word signifies, like a sheet spread, or a curtain drawn out. This includes all that is visible above the earth, between it and the third heavens, the air, its higher, middle, and lower region, the celestial globe, and all the orbs of light above; it reaches as high as the place where the stars are fixed, for that is called here the firmament of heaven, Ge 1:14,15, and as low as the place where the birds fly for that also is called the firmament of heaven, Ge 1:20. 2.”

John Wesley · Explanatory Notes upon the Old Testament (on Gen 1:6)

Reformed Notable voices

“Let there be a firmament The work of the second day is to provide an empty space around the circumference of the earth, that heaven and earth may not be mixed together. For since the proverb, to mingle heaven and earth,' denotes the extreme of disorder, this distinction ought to be regarded as of great importance. Moreover, the word rqy (rakia) comprehends not only the whole region of the air, but whatever is open above us: as the word heaven is sometimes understood by the Latins.”
