There was a time just a few decades ago when many church emphasized eschatology beyond the subjects of heaven and hell. Although someone might challenge these statistics, I have read that at least 150 chapters of the Bible are predominantly about the End Times and about 14% of the Bible deals with the End Times. I can believe that.
So, the expanded questions sounds like this: If you consider how much fo the Bible deals with the End Times, would you guess that your church's teaching/preaching ministries resemble the emphasis of Scripture?
Book by book exposition would result in the perfect balance, if preachers and teachers of the Word do not skip or rush through sections. If I preach through Ezekiel and do not address the Temple measurements or the Gog Magog war, for example, that would decrease my emphasis. If I take great pains with Matthew 1-23 and then rush through 24-25, I am covering the text (in a sense), but I am not giving equal time to the prophetic section. The reverse is also true!
So please consider a bit before answering!
