Two institutions that are supposed to produce formed, committed, consistent men are failing at the same task in the same way and for almost exactly the same reasons.
The numbers are not subtle. Lifeway Research's 2025 State of Discipleship study found that only 8% of pastors strongly agree they are satisfied with discipleship and spiritual formation in their churches. Nearly half of all pastors expressed clear dissatisfaction with the current state of discipleship. Most churches have no specific method for measuring it and almost none believe they are doing it well.
Now think about gym retention data. Most men who join a gym stop going within three months. Most men who commit to a training program abandon it before it produces meaningful results. The dropout rate for strength training programs in the general population is among the highest for any health behavior.
Two different institutions. Same failure. Same reason.
What discipleship and training have in common
Both require sustained, repeated effort over a long period of time to produce results that matter. Both produce results that are invisible in the short term and compounding over years. Both require showing up when you do not want to, when nothing is visibly moving, when the gap between where you are and where you want to be feels too wide to close by one more session or one more service.
And both fail for exactly the same reason: the system in place was designed for participation, not formation. It measures attendance rather than transformation. It tracks how many people showed up rather than whether the people who showed up became something different from what they were before.
A church that counts Sunday attendance as the metric of discipleship success and a gym that counts membership sign-ups as the metric of fitness success are running the same broken model. They are measuring the input and calling it the output.
What formation actually requires
It requires a system that makes real, specific, escalating demands over time, recognizes progress against those demands, holds men accountable when they fall short, and provides genuine community with other men who are doing the same thing.
This is what the military does. This is what serious athletic programs do. This is what the early church did, before Sunday attendance became the primary metric of Christian formation.
"Iron sharpens iron, and one man sharpens another." (Proverbs 27:17)
Sharpening is not a passive process. It requires friction, contact, and something hard enough to do the actual sharpening. A church that asks nothing of its men, offers no friction, and tracks no transformation is not sharpening anyone. It is providing a comfortable weekly experience that leaves men exactly as it found them.
The same is true of the gym that provides equipment and a membership card and calls the rest the member's responsibility. The equipment does not sharpen anyone. The friction of a program with real demands, applied consistently with accountability, does.
The fix, which is the same for both
Stop measuring attendance. Start measuring transformation.
For the church: what is the man who showed up last year different from the man who shows up today? What does he know that he did not know? What has he done that he would not have done? If those questions have no answers, attendance is the wrong metric.
For the gym: is the man who trained last year stronger, more capable, more consistent, more disciplined than the man who started? If training is not producing a man who is demonstrably different, the program is producing attendance, not formation.
The fix in both cases is building around transformation rather than participation. Real demands. Real accountability. Real recognition of progress. Real community with other men who are doing the same work and will not accept the excuses that comfortable systems accept without question.

FAQ
What does the Lifeway discipleship research show?
Only 8% of pastors strongly agree they are satisfied with discipleship in their churches. Nearly half expressed clear dissatisfaction. Most have no specific method for measuring discipleship.
Why do most men stop going to the gym within three months?
Because most gym systems measure membership, not transformation. They provide equipment and access but no real demands, no accountability, and no friction that would produce lasting formation.
What is the difference between participation and formation?
Participation measures showing up. Formation measures what is different about the man who showed up. A system that tracks attendance without tracking transformation is measuring the input and calling it the output.
What does iron sharpening iron mean for training communities?
That the relationship which changes a man involves friction, contact, and something hard enough to do the sharpening. Sitting next to other men who are also comfortable does not sharpen anyone.
How do I find a training community with real standards?
Look for communities where attendance is assumed rather than celebrated, where progress is tracked and expected, and where showing up consistently is the minimum rather than the achievement.
"Iron sharpens iron, and one man sharpens another." (Proverbs 27:17). Find the friction. Build the system. Become something different from what you were.
