Five years of preaching, how far have I gotten?

While planning out my sermons up through Easter (I normally only plan that far ahead in advance of Christmas and Easter, so as to ensure that my sermon focus lines up with those holidays), I took the time to look back on the past five years here at First Baptist of Franklin to see how much of the text of the Bible I have preached, verse by verse.  This tally doesn't include the five years prior at First Baptist of Palo, as that was a different audience, thus any repeated texts from then don't enter into it.

The results were interesting, to me at least.  I've completed preaching through six books of the Bible, verse by verse, start to finish: Ruth, Jonah, the Gospel of Luke, Philippians, Titus, and James.  I've also completed chapters 1-18 of Acts, and chapters 10-32 of II Chronicles.  Throw in five messages out of Isaiah (one of the Lenten series), and a couple out of Matthew (an Advent series), plus a half dozen Psalms, the sections of 1 Samuel covering Hannah and Samuel, and the first three chapters of 1 Corinthians (my current sermon thread), and that about covers it.  The stack of yellow legal paper I write my sermons upon is now impressively high.

Which makes me wonder: If, Lord willing, I continue on here at 1st Baptist of Franklin for, say 20 more years, to pick a round number, how close to preaching through the whole Bible will I be able to come?  The Bible contains sixty-six books, of varying length, Luke is the only one of substantial length I've finished thus far, but Acts and II Chronicles will be finished in a year or two.  In theory, after 25 years, I might be halfway to preaching through the whole Bible.  What would it take to get the whole way through, and has anyone really accomplished that goal while still doing justice to each phrase, sentence, and verse?  I don't think I have the additional 50 years of preaching in me that it might take for me to finish, but who knows, after all, I am training for the Oil Creek 50k again this year.
