Charles Spurgeon Commentary Genesis 1:3-4

"And God said, Let there be light: and there was light. And God saw the light, that it was good: and God divided the light from the darkness." — Genesis 1:3-4 (ASV)

"Light be." "Light was." God had but to speak the word, and the great wonder was accomplished. How there was light before there was any sun — for the sun was not created until the fourth day of the week — it is not for us to say.

But God is not dependent upon his own creation. He can make light without a sun, he can spread the gospel without the aid of ministers, he can convert souls without any human or angelic agency, for he does as he wills in the heavens above and on the earth beneath.
