Passage
God called the light “day”, and the darkness he called “night”. There was evening and there was morning, the first day.
God called the light “day”, and the darkness he called “night”. There was evening and there was morning, the first day.
Genesis 1:3 God said, “Let there be light,” and there was light.
Genesis 1:4 God saw the light, and saw that it was good. God divided the light from the darkness.
Genesis 1:5 God called the light “day”, and the darkness he called “night”. There was evening and there was morning, the first day.
Genesis 1:6 God said, “Let there be an expanse in the middle of the waters, and let it divide the waters from the waters.”
Genesis 1:7 God made the expanse, and divided the waters which were under the expanse from the waters which were above the expanse; and it was so.
The verse centers on "called", "light", "darkness", "night", "evening", "morning", and "first". It is saying that the contrast between light and darkness marks a real divide in how people respond to God's work.
The nearby context moves from verse 4's "God saw the light and saw that..." into verse 6's "God said Let there be an expanse...", so "called" and "light" belong inside that flow. In Creation Begins, the local focus is creation, God's sovereignty, the Spirit's presence, and light.
A plain takeaway is to answer the verse's own emphasis on "called" and "light" with trust shaped by these words, not by a vague optimism outside the passage.
