Again:
It can be taken as a time-compressed description of the evolution that took place over millions of years,
according to a presentation by 9Mark Dever and his mentor Roy Clements to the Cambridge Inter-Collegiate Christian Union:
CICCU • Dever and Clements on Christians and Science (audio file)
38:30-39:55
CLEMENTS: "In fact if you think about it,
Genesis chapter One does portray an evolutionary model. It would have been very easy for the ancient author, knowing nothing at all about evolution, to have simply said the whole of the universe suddenly sprang into being by a single divine fiat, with no progress, no development at all, but no, he spreads it out over seven days, and he says that material things emerged first: light, and the earth, and the heavens, and then plants before animals, and marine animals come before land animals, and the human race comes only at the very end.
In an astonishing way, he anticipates the general sort of evolutionary scheme, without any of the evolutionary details. So
I don't have any great difficulty in accepting that if evolution was the way it happened, that God might have used such a mechanism for the production of the variety of species that we see, and I don't find any great difficulty harmonising that with Genesis One.
But there are some Christians who feel that the seven days have to be taken with a greater degree of literalness than I feel is necessary, and they must look for another solution to the problem."
1:12:00-1:13:20
DEVER "
The word Yom there in the Hebrew is used very similarly to the way we use the word
Day, and it
means many different things. I'm not sure I want to say exactly what Roy said on that, but I think,
as a Christian who certainly believes in the truth of scripture there's nothing he's said that's inconsistent with that."
CLEMENTS: "
If it were a twenty four hour day, I favour the view that it was a twenty four hours of revelation, maybe
the prophet saw the vision over the space of seven days, but I don't think the prophet could possibly have been given an actual time scale to set against the things he was seeing happen. They had to have taken place in a time-collapsed way. He couldn't possibly have seen them, in my view, across the spectrum of the time the took,
if they took millions of years, as science would say. He would have to have seen it in a time-collapsed way."
DEVER - "
And I would say of course He could have done it in that way, and of course the prophet could have seen it that way, but the point is the word doesn't necessitate, the word
Yom, doesn't necessitate you or me or Roy looking at it any one of those —"
CLEMENTS - "
There are a whole host of ways of harmonising Genesis One with scientific accounts of origins. Some are seven-day Creationists, Young Earth view, I respect that view, but I don't hold it myself."
