GENESIS 1:17
God set them in the firmament of the heavens to give light on the earth, [Genesis 1:17 NKJV]
God set these lights in the expanse of the sky to shine upon the earth, [Genesis 1:17 BSB]
Bible Teacher
God did not just place these Lights in the heavens just because they were Lights, but He placed them in the heavens because they would have to give light to the earth below through the heavens. Not that God entrusted those Lights with the heavens for the earth, but that God entrusted the heavens with those Lights for the earth. God trusted the heavens would neither prevent nor cover those Lights inside them; but that the heavens will share the light of their Lights to the earth below them.
Better for the earth that the heavens always have and keep those Lights for all the earth, than for the earth to have custody of those Lights for now: For now all the earth may benefit the light of those Lights because they are not on earth but in the heavens; for the heavens who are open and faithful in displaying, revealing and sharing them to the inhabitants of the earth.
Commentaries:
We see the earth full of riches, abundance of resources and foods, but yet there are poverty and hunger on earth because some parts, some men and some animals, of the earth greedily and selfishly hoard and hide these things from the others on the same earth. Even the gospel light of the Lord Jesus Christ have not yet reached all parts of the world either because some are not sharing that gospel light with other parts of the world or because there are some opposing/hindering the spreading of the gospel light to all parts of earth. But as you can see, all the face of the earth do enjoy those Lights because God set or placed those Lights in the heavens to give light on earth. Nothing like their light being unaffordable to the poor or unreachable on earth.
[Psalms 19:4-6 FBV] — "Yet what they say is heard all over the earth; their message goes to the whole world. God has made a home in the heavens for the sun. It's like a bridegroom coming out of his room, like a fit athlete happy to run a race. It rises on one side of the heavens and travels across to the other. Nothing is hidden from its heat."
Share the Light God placed within you, not to glorify yourself but to give light to those on earth and those below your position.
