The Logos blog is pushing classic sermons. The normal sermon price is 14 cents, but for a short time, you can purchase at the rate of 7 cents per sermon.

That made me wonder. Apparently in the 1st century, some evangelists charged for the good news. Probably more than 7 cents, though slaves weren't rolling in drachmas.
On the forum, pastors appear to use a minimum of a day to prepare a sermon. That's what my dad said too. So, let's say $240 cost of production. Add in travel expenses (for the Apostle Paul's competitors ... Paul made tents).
So, would you pay $240 for a sermon? Probably not. What if you ratcheted the bidding downward, where would the average pew-sitter end up. $20. Doubt it. $10? Here in Sedona, that's max for similar events.
Of course, we're talking eternal life. Ok. 7 cents.
