The Hours You Used to Spend in Commentaries — Where Do They Go Now?

The most time-consuming part of sermon prep usually isn’t the writing. It’s the choosing. Prepare Romans 4 and you’re facing dozens of commentaries, several strands of original-language analysis, and a bottomless pile of background scholarship. The problem was never a shortage of material — it’s that narrowing hundreds of possible sources down to the handful that actually fit this text, this week, this congregation takes real time. That’s the paradox: more available material tends to mean more prep time, not less.

What the hours actually look like

This isn’t an abstract claim — the numbers back it up. LifeWay Research found that the average U.S. Protestant pastor spends roughly 14 hours a week preparing a Sunday sermon, with other surveys putting the range at 8 to 13 hours depending on church size and experience, and pastors at larger churches with more study demands reporting 15–25 hours on a single message. Most of that time isn’t spent writing. It’s spent doing exactly what the section above describes — opening commentary after commentary, cross-checking the original language, tracking down background scholarship — before a single sentence of the sermon itself gets written.

That’s the specific stretch a Didymus Lab report compresses. Instead of spending hours pulling the five sources that actually matter for this week’s text out of a shelf of fifty, you get them assembled from one passage entered once. It doesn’t touch the writing — it touches the research phase that eats the largest share of those 14 hours, freeing that time for what happens after the sources are already in hand.

The value isn’t search — it’s selection

Search itself stopped being the hard problem a long time ago. Finding material isn’t difficult; narrowing a hundred results down to the five you’ll actually use this week is. That’s consistent with what Barna Group’s 2026 survey found: the single most common use pastors report for AI is idea brainstorming, at 50%. What pastors are reaching for isn’t new knowledge — it’s help narrowing an already-vast field down to what’s relevant right now.

That’s the job a Didymus Lab report does. Drawing on dozens of scholarly databases — original-language biblical texts, verified commentaries, ancient Near Eastern and Greco-Roman background sources, patristic writings — it pulls together only what actually fits the specific passage and situation you requested. It’s the difference between being handed the run of a library and being handed the five books you actually need on your desk this week.

The saved time doesn’t disappear

What matters is where that time goes. Less time spent hunting through sources doesn’t make sermon prep lighter — it moves that time to where it belongs: wrestling with the text in prayer, picturing the specific people in the pews and working out how the passage lands for them, and the visits and conversations no report can substitute for. The goal is a clean division of labor — AI handles what it’s actually good at (narrowing a wide field of material), and the pastor keeps what only a pastor can do (deciding what to say with it, and who to go see). That’s the direction this tool is built toward.

Last in this series: the most fundamental question of all — could this report be quietly feeding me something theologically off?
