I am on short rations timewise this week, so a bit of reliance on the writings of others ...
Is there any virtue in expounding a literal seven day creation? Possibly. An appreciative but critical perspective heads towards this conclusion:
"So I do not think that Ken Ham–style creationists should get to rewrite biology textbooks according to their very peculiar reading of Scripture. But I admire their bullheadedness. They have gotten lost in the woods while trying to protect the big truths of Christianity: that God created the world, that we are dependent on him, that we owe him everything, and that he loves us even though we are sinful. In the world most of us inhabit, day to day, the world of lovers, wriggling kids, disease, war, and death, the sureness of God's love is relevant in a way that the details of early hominid fossils never will be, glorious as they are. Have some perspective, people."
