Fighters spend years training their minds to stay composed under pressure.
Research on combat athletes shows that mental toughness is linked with lower competitive anxiety and better emotional control during high-stress competition (Slimani et al., 2023; PMID 37949383).
They are not fearless.
They learn how to function in the presence of fear.
Neuroscience helps explain part of this.
When the brain detects danger, the amygdala helps trigger the fear response, while areas of the prefrontal cortex help regulate emotion and guide decisions, helping a person stay focused rather than react impulsively (LeDoux, 2000; PMID 10845062; Arnsten, 2009; PMID 19455173).
When I say fighter here, I am referring to both male and female combat athletes.
Scripture uses similar language. Paul writes that βwe wrestle not against flesh and bloodβ (Ephesians 6:12).
Wrestling is close contact. It is personal and relentless. The Bible reminds us that the Christian life is not passive.
We are called to stay sober-minded, to know the opponent, and to stand ready by putting on the full armor of God (Ephesians 6:11; 1 Peter 5:8).
