In our time a considerable number of theories have arisen denying that the creation, as we know it, took place in six twenty-four-hour days. Common to these theories is the acceptance of the dominant scientific view that the earth and life on it are very old. Many consider the biblical account to be primitive, mythological, and untenable in light of modern scientific knowledge. (v. 1, p. 120)
As a Reformed Christian myself, Sproul's statements are disappointing on many levels. Traditionally, he has interacted with top-level scholars, but it seems as though he has been persuaded on this issue by less-than credible biblical and scientific scholarship. Sproul’s Calvinist bravado of intellectual courage and independence rings a bit hollow to me now.
