The point of the article is that it would be nice to mix sola scriptura with traditional, more contemplative, worship style. More Bach, less Maranatha Music Company.
(Not for every church or every service. Emotionalism is motivating and spiritual to a large number of people, perhaps a majority.)
My point is, most engineers and programmers don't care about that anyway. No matter the music style, it'll always be too simplistic for programmers. You might as well be trying to market an investment firm to programmers as DIY investors and spend time debating about the best colors for your banner ads and ignoring the fact that the programmer investors are looking for firms that can supply the best market data and trading options.
We should market Jesus to them by pointing out that Jesus Himself said to study the Scriptures. We should tell them there's so much, much more to God that what little you hear from the normal sermon or church media -- and you can find it in the Bible.
I'm telling ya, Christianity is popular among programmers and engineers in Alabama. I have no doubt it's related to 3/4ths of the population of Alabama being Protestant.
