One should always be ready to provide a reason for the hope they have within (cf. 1 Pet. 3:15), but when it comes to creation and biblical interpretation, it is all too common for earnest and well-meaning Christians to waffle or throw up their hands when pressed on the issue. One theorist who has had an exceptional amount of influence over post-Darwinian theology is Hugh Ross, and Day or Age cuts through a lot of the jargon to clearly summarize and critique Ross's theory. Additionally, McGee addresses, with respect and poise, why evangelicals and biblical inerrantists must wrestle with the issue of creationism because of how it affects the overall interpretation of Scripture, how New Testament writers thought about Genesis 1-11, and the myriad theological concepts hinging on a proper perspective on creationism. Day or Age is accessible without being simplistic and makes a strong case for evangelicals to revisit their stance on old-earth creationism, either by intentional thought or by tacit agreement.
