Passage
And God called the light day, and the darkness He called night. And there was evening and there was morning, one day.
And God called the light day, and the darkness He called night. And there was evening and there was morning, one day.
Genesis 1:3 Then God said, “Let there be light”; and there was light.
Genesis 1:4 And God saw that the light was good; and God separated the light from the darkness.
Genesis 1:5 And God called the light day, and the darkness He called night. And there was evening and there was morning, one day.
Genesis 1:6 Then God said, “Let there be an expanse in the midst of the waters, and let it separate the waters from the waters.”
Genesis 1:7 So God made the expanse and separated the waters which were below the expanse from the waters which were above the expanse; and it was so.
The verse centers on "called", "light", "darkness", "night", "evening", and "morning". 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 "And God saw that the light was..." into verse 6's "Then God said Let there be an...", 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.
