No one knows what the nature of the lights source the first 3 days. It could have been an angel as they likely were created on day one. They are beings of light, and it would make sense if they were the source. But it could have been anything. We just know light existed before the sun. The author is explicit about that. I don't know why people fight it.
No one knows? Then, why do you act like you know what it can not be?
Again.. we have some hints to be found in the Bible that make something to be known.
1 John 1:5
This is the message which we have heard from Him and declare
to you, that God is light and in Him is no darkness at all.
That was too easy... See? You say YOU KNOW that can not be the provision of light before the sun was put into motion by God? How can you say no one knows? But, you seem to know? Hell, No One?
Now, look here at what the serious Bible student would have stored away in his/her frame of reference, enabling them to think with what I have shared with you, but you stomp in a mental huff, and closed your mind to..
Revelation 21:22-24
I did not see a temple in the city, because the Lord God Almighty
and the Lamb are its temple. The city does not need the sun
or the moon to shine on it, for the glory of God gives it light,
and the Lamb is its lamp. The nations will walk by its light, and
the kings of the earth will bring their splendor into it.
1 Timothy 6:15-16
which God will bring about in his own time—God, the blessed
and only Ruler, the King of kings and Lord of lords, who alone
is immortal and who lives in unapproachable light, whom no one
has seen or can see. To him be honor and might forever. Amen.
See?
Big hint! One of God's attributes is being a bearer of great and glorious light!
This attribute of God may explain why Lucifer and the morning stars were created originally to be light bearers. For, as "sons of God" they were also created in the image of God.
That's off on a tangent to you? When I am nailing a solution home?! Come on! Let some daylight into that closed mind of yours! You say no one knows what provided the light. But, now? Act as if you do know what it could not have been! Stop walking in darkness and let the Word of God shine into your heart. You might just like the answer if you do.
For those Christians who study and learn sound doctrine and mature to glorify Christ while on earth? Part of their reward may startle to realize! More LIGHT!
Daniel 12:3
Those who are wise will shine like the brightness of
the heavens, and those who lead many to righteousness,
like the stars for ever and ever.
Matthew 13:43
Then the righteous will shine like the sun in the kingdom
of their Father. Whoever has ears, let them hear.
Note:
"Whoever has ears, let them hear."
You know there is a big difference between
"no one knows" what produced the first days of light With,
"no one can know." You have chosen the latter?
Colossians 2:2-3
My goal is that they may be encouraged in heart and united
in love, so that they may have the full riches of complete
understanding, in order that they may know the mystery of
God, namely, Christ, in whom are hidden all the
treasures of wisdom and knowledge.
Please.. Put away your pet theory that is based upon secular reasoning.
Treasures of wisdom and knowledge to be found in the Word of God has been hidden from secular thinking and and buried beneath the surface of Scripture.
One must dig in and reach some depth. That only comes through a process of error and corrections in humility. Grace is denied the proud. But, greater grace is given to those who have learned to be humble.
1 Timothy 6:15-16
which God will bring about in his own time—God, the blessed
and only Ruler, the King of kings and Lord of lords, who alone
is immortal and who lives in unapproachable light, whom no one
has seen or can see. To him be honor and might forever. Amen.
That speaks not of the sun. But, God's Son.
Please... keep an open mind.
