The doctrine of inerrancy–that the Bible is without any kind of error whatsoever–is closely tied to the practice of expository preaching—teaching line-by-line, verse-by verse. Their connection makes sense: if the Bible is perfect, than every word of it should be brought to bear on the Christian’s soul.
Thus one could argue that there is no real concept of expository preaching without a true understanding of inerrancy.
On Monday (October 27), the church I pastor is hosting a conference with John MacArthur and Mark Dever. They are going to spend the day explaining this connection, and making a plea for people to not only understand inerrancy and expository preaching, but to seek out churches that model a high regard for both.
