In the preface he makes a good point about a false dichotomy, something that I have written voluminously on in print, audio, and this blog. This either/or mindset is found in many believers.
But some Christians, although diligent students of Scripture in every other area, avoid the topic altogether and appear content to place themselves in the category of undecided. Some even seem proud of their agnosticism, as if ignorance about the meaning of biblical prophecy is evidence of a commitment to more significant matters. But affirming the centrality of the gospel should not mean dismissing the importance of how God will accomplish the restoration of all things to Himself. Scripture reveals too much about the subject of eschatology for Christians to be content in the dark, especially those who preach the Word and shepherd the flock (source).
