Is there nothing new under the sun?

There might not be anything new under the sun as Ecclesiastes tells us, but there sure is something new under the One who sits above the sun. “Newity” is dependent upon which light one stands under—the light of the sun or the light of the Son.

Plus, what in the world do we mean when we say “there is nothing new under the sun.” There might not be any new matter being created, but surely there are new things being created with that matter.

Do we mean that the nature of man, with all of its cyclical behaviors, habits, attitudes, sins, desires, needs, and wants is unchangingly consistent, and therefore is never new but always old news? Could that be what is meant when the Scriptures say that “there is nothing new under the sun?”

Or could it be that the fact of there being “nothing new” is subject to a specific context—specifically, the context of an un-regenerate heart?

Forgive me if none of this makes any sense.
