Passage
To shine in the firmament of heaven, and to give light upon the earth, and it was so done.
To shine in the firmament of heaven, and to give light upon the earth, and it was so done.
Genesis 1:13 And the evening and the morning were the third day.
Genesis 1:14 And God said: Let there be lights made in the firmament of heaven, to divide the day and the night, and let them be for signs, and for seasons, and for days and years:
Genesis 1:15 To shine in the firmament of heaven, and to give light upon the earth, and it was so done.
Genesis 1:16 And God made two great lights: a greater light to rule the day; and a lesser light to rule the night: and the stars.
Genesis 1:17 And he set them in the firmament of heaven to shine upon the earth.
The verse centers on "light", "shine", "firmament", "heaven", "give", "upon", "earth", and "done". It is saying that the verse draws attention to "light" and "shine", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 14's "And God said Let there be lights..." into verse 16's "And God made two great lights a...", so "light" and "shine" belong inside that flow. In Genesis context, the local focus is creation, human rebellion, covenant promise, and God's providence.
A plain takeaway is to answer the verse's own emphasis on "light" and "shine" with trust shaped by these words, not by a vague optimism outside the passage.
