The Paper

What this paper is

This paper reads twelve short passages of Scripture alongside the last few decades of peer-reviewed research on stress, attention, sleep, relationships, and habit. Each section describes what the studies actually found, explains what seems to be happening in the brain and body, says plainly what the studies cannot tell us, and closes with practices for living it out. A final section gathers those practices into an everyday rule of life.

It began in a men's Bible study working through Tony Evans's No More Excuses, where the theme is taking responsibility for how we live. The research turned out to be useful there for a simple reason: it helps explain why the disciplines Scripture asks of us are not arbitrary.

The aim is neither apologetics nor debunking. It is closer to what a surveyor does when two independent maps of the same ridge line up: you note the agreement, check your instruments, and let it sharpen your attention.

A starting point, not the last word

The paper is a first step. It holds to one ground rule, convergence, not proof: the verse does not need the study, and the study does not prove the verse. Some findings rest on large trials and some on a single small study, and the paper says which is which. Every practice on this site carries a label for the strength of the evidence behind it. The research will keep moving, and the paper will be revised as it does.

The paper itself stands as written. It is the paper that started the process, and the work keeps growing: 24 further passages have been added since, each written to the same pattern, with its own sources and five practices.

How to read it

Start at the beginning. The introduction and note on method take about ten minutes and explain how to read everything that follows.
Or start where you are. Each passage stands on its own. Pick the one that speaks to this week, whether that is worry, anger, loneliness, or rest.
With a group, use the study guide: one passage per meeting, with discussion questions and a practice to try.
To put it into practice, go to the thirty-day start and choose three practices.
With a question, ask the guide. It answers from the paper and points you to the right page.

What's inside

By the numbers

12 passages
60 practices, each labeled by evidence strength
196 sources, each checked

Those are the paper's own numbers. With the additions, the site now has 36 passages, 180 practices, and 245 sources.
