But ultimately, if God did create this realm in which we exist, from the furthest star in the universe to us, to the basic, smallest micro-part that makes up all the physical 'things' of this earth on which we live, as He seems to clearly explain that He did, then wouldn't not believing that make one an unbeliever in what the Scriptures reveal to us?
I mean, I know a God who can turn back the shadow of the sun. I know a God who can hold the sun over a specific point of the earth for hours rather than the brief minutes that it normally moves across a place on the earth. I know a God who can cause the deaths of just the firstborn of man and animal in an entire city in one night. I know a God who can make an iron ax head float. I know a God who can place lovingly inside the womb of a young woman His very essence in a human baby, that had no human semen to begin its life. I know a God who can tell me 483 years before the Messiah came, that the Messiah would be here in 483 years.
So for me, believing in a God who can merely command an entire universe comprised of trillions of stars and planets and asteroids and all that make up the heavens around us with just commanding it to be and it is immediately so, is no problem. But of course, what God made has a physical make-up and man keeps trying to find all of the answers to life in the physical make-up of the things of this existence. Relying on the things that God has made and not the things that God has told us, to determine 'how' we got here.
Well, a Christian who believes God used a process called the Big Bang to enact the creation of the universe isn't denying God is the "Big Banger." God
could act in supernatural ways within the universe
all the time, if He wished to, accomplishing what He wills solely by miraculous acts instead, constantly violating the natural laws of the universe He made. But He doesn't. Instead, He acts mostly within, and through, the various Laws of Nature that He instituted, only very rarely contravening those laws in the fulfillment of His will. There has been, after all, only
one virgin birth, only
one instance of God halting the Sun for a time, only
one floating axe-head, only one instance of a man walking on water, etc. These things are remarkable mainly as consequence of their singular, natural-law-confounding character. We don't take any notice of events that are common, right? No one points in wonder at a leaf falling to the ground, or gasps in awe at a person walking their golden lab down the street. It isn't, then, God's way of acting - in our world, at least - to regularly suspend natural law in exertion of His will.
Why, then, should I think that the manner in which God created the universe is any different? Of course, creation
ex nihilo happened without the constraint of any natural law, but the instant time, space, matter and energy came into being, the natural laws governing them began to work to order and confine the universe and its physical operations. Holding to this understanding of the beginning of the universe doesn't in any way diminish God's sovereignty, or power, nor does it do violence to the record of Scripture. It also aligns well with what science has uncovered of the instant of creation. It's odd, then, to me to encounter Christians who bridle at the idea that God acted in formation of the universe through the natural laws He instituted.
And despite everyone saying it's not a particularly important issue, It was important enough for God to point it out to us as a part of His law to us. So, I think, hmmmmmm, when I read over that part where the Lord says, in establishing the practice of the Sabbath, "Six days you shall labor and do all your work, but the seventh day is a sabbath to the LORD your God. On it you shall not do any work, neither you, nor your son or daughter, nor your male or female servant, nor your animals, nor any foreigner residing in your towns. For in six days the LORD made the heavens and the earth, the sea, and all that is in them, but he rested on the seventh day. Therefore the LORD blessed the Sabbath day and made it holy."
Well, again, read John Lennox's book "Seven Days that Divide the World." He shows in it that there are a number of legitimate, but differing, ways of interpreting the Genesis account of creation. Before you become too dogmatic about which interpretation to adopt, perhaps give these other ways of understanding the Genesis account of creation some careful consideration.
