Does it matter?
I am not making light of the topic, but considering the scope of pose and poetry in the Scriptures, is it not better to state with certainty as the Scriptures do:
15He is the image of the invisible God, the firstborn of all creation.
16For by Him all things were created,
both in the heavens and on earth, visible and invisible, whether thrones or dominions or rulers or authorities—all things have been created through Him and for Him.
17He is before all things, and in Him all things hold together.
Does Genesis 1 give all the details and facts of creation? Of course not!
God left such an abundance undiscovered for humankind to argue over, yet the certainty is that God creates. He did so (Imo) for two reasons: 1) To allow for humans to become so self absorbed as to confirm their foolish minds in darkness, and 2) To allow for believers to be all the more encouraged and certain of the authority and knowledge of the Creator.
He is not haphazard, desperate, nor unskilled, but takes time, takes patience, and demonstrates such intricacy that humankind even in this modern age have yet to reach the full depth of any science, but merely tread on the surface disclosing what we might scratch up.
He did not stop creating but according to Scriptures continues:
1“Do not let your heart be troubled; believe in God, believe also in Me.
2“In My Father’s house are many dwelling places; if it were not so, I would have told you; for I go to prepare a place for you.
3“If I go and prepare a place for you, I will come again and receive you to Myself, that where I am,
there you may be also.
What I haven't found in Scriptures is if God ever stops creating.
My own opinion (which is worthless) is that He does not, but as the glory of the new heavens and earth radiate His glory, the book closes, and some of us long to know more.
