Bibles and Barbells: Building Confidence

Confidence is not something we are born with. It is a trait developed through traversing difficult situations or problems and overcoming them. Confidence is a byproduct of problem-solving and perseverance, and therefore it cannot simply be “given.” It must be built — slowly, intentionally, and often through resistance.

This is one of the reasons strength training, especially working under a barbell, can be so transformative. Every time you step up to the bar, you are facing a clear and measurable challenge. The weight is either lifted or it isn’t. At first the bar may feel heavy, awkward, even intimidating. But week after week, as you continue to train, something begins to change. The weight that once stopped you starts to move. Your posture improves. Your breathing steadies. Your mind calms. And gradually, you begin to believe what your body is proving — that growth is possible.

In many ways, the barbell becomes a training ground for confidence. Each set provides critical stress. Each rep reminds you that strength comes at a cost. Over time, the gym becomes a place where a man learns to confront resistance rather than avoid it. This principle shows up throughout Scripture as well. Hebrews reminds us,

“No discipline seems pleasant at the time, but painful. Later on, however, it produces a harvest of righteousness and peace for those who have been trained by it.” - Hebrews 12:11 NIV

Anyone who has finished a hard set of squats understands this idea immediately. The bottom of the 5th rep of a set of heavy squats is very uncomfortable, but the discomfort is temporary, and reaping the rewards accumulated over time is worth the trouble.

The apostle Paul often refers to athletic discipline as a metaphor for the Christian life. In 1 Corinthians he writes,

“I strike a blow to my body and make it my slave so that after I have preached to others, I myself will not be disqualified for the prize.” - 1 Corinthians 9:27 NIV

Paul is describing intentional training: the kind that requires effort, structure, and full-hearted commitment. In the same way a lifter develops strength through consistent work, a believer grows through disciplined living and perseverance. I believe Paul uses this metaphor because caring for the body like we care for the spirit seems to have this multiplying effect, each playing and improving upon the other.

What’s interesting is that modern research actually supports what many lifters already experience. Studies on resistance training show that strength training increases self-efficacy — the belief that you are capable of handling challenges. As someone gets stronger, their confidence in their ability to solve problems and overcome obstacles increases. This example has been observed over and over. Researchers also consistently find that resistance training improves resilience, mood, and stress tolerance. In other words, the process of getting stronger physically helps build mental and emotional strength.

This makes sense when you consider what happens in the gym. A lifter faces a problem: a heavy barbell. The solution is not immediate. It requires practice, recovery, and persistence. Over time, muscles grow stronger, the nervous system adapts, and technique improves. Each successful lift reinforces a simple but powerful message: I can do hard things that I couldn't do before.

That message carries into the rest of life. A man who has learned to stay composed under a heavy squat is often better prepared to stay composed under pressure at work, at home, or in leadership. Strength training does not create character on its own, but it certainly develops the habits that shape it. It's hard not to learn the lessons of patience, consistency, humility, and effort if you're showing up to the weight room or in your garage gym on a consistent basis.

Faith deepens this process even further. Confidence for the Christian man is not rooted only in his own physical strength, but in the strength God provides.

“I can do all this through him who gives me strength.” - Philippians 4:13 NIV

 For a lifter, that doesn’t mean every barbell will suddenly feel light, but it reframes the mind. The effort itself becomes meaningful. Discipline becomes an act of stewardship, and perseverance becomes a reflection of trust.

There is also a quiet confidence that grows when a man sees progress over months and years rather than days. Strength training teaches patience in a world obsessed with instant results. It shows that real growth happens gradually. Just a few pounds here and there, one workout at a time, day after day, week after week, and so on. Science calls this progressive overload (adaptation), while Scripture calls it hupomonē, the Greek word that means "to abide under" or "patient enduring."

James describes it this way: “Let perseverance finish its work so that you may be mature and complete, not lacking anything.” (James 1:4 NIV). In both faith and training, the process matters. The repetition matters. The willingness to keep going when progress feels slow matters.

Over time, the barbell becomes more than just a tool for building muscle. It becomes a mirror that reflects what a man is becoming. Each challenge overcome builds not arrogance, but steady, grounded confidence. The kind that comes from experience. The kind that has been tested.

Confidence, then, is not something handed to us. It is formed through resistance, perseverance, and growth. Under a barbell and under the guidance of God, men learn the same lesson: strength is built one challenge at a time, and the confidence that follows is earned through the process.
