From William Edgar’s Introduction to the Second Edition of Van Til’s An Introduction to Systematic Theology: Prolegomena and the Doctrines of Revelation, Scripture, and God:

Various post-evangelical Protestants espouse their own versions of these schools [Christian alliance with kinds of post-Kantian views, that is, postmodern philosophy]. Stanley Grenz was drawn to postmodern models advocating, as he did, a christological center and a “non-linear” outline for redemption, over against the older creation-fall-redemption ground motive. The problem with such accommodations is that they are not able to relate the human creature with God the Creator in objective categories. Lacking a true theology of the Creator-creature relationship, they cannot assert the historical nature of the fall into sin from the state of integrity. And because of this they cannot fully appreciate the moral revolution that led to the fall, and so the problem in the human condition is not so much moral guilt as it is finitude, at least to some extent. As a result, redemption is not fully of God’s mercy, with a transition from wrath to grace in history, through Christ. Instead they must grope after divine liberation, turning revelation into a project of the self, rather than seeing it as God’s merciful self-disclosure to fallen humanity (3).
