What the Bible Says About Self Control
The short answer
When the Bible talks about self-control, it rarely sounds like a personality trait—something some people are born with and others simply lack. In Galatians 5:23, self-control appears as part of the "fruit of the Spirit," something that grows in a person over time rather than something they grit their teeth and produce. In 2 Peter 1:6, it sits in the middle of a chain of qualities believers are told to add to their faith, one building on the next. And Proverbs 25:28 gives us the sharpest image of all: a person without self-control is like a city "broken down and without walls"—defenseless, open to whatever wanders in.
What holds these verses together is honesty about the human heart. Second Peter includes a bracing list of vices—greed, injustice, runaway appetites—and the temptation, when reading a list like that, is to picture other people. N.T. Wright pushes back on exactly that move. The tendencies named in those verses, he argues, live in every one of us, and self-control is the daily work of holding them back: putting wrong desires to death and deliberately growing right ones in their place.
That reframing matters. Self-control in Scripture is not smug distance from "those wicked people," and it is not moral scorekeeping. It is more like tending a garden or maintaining a city wall—ongoing, unglamorous, and necessary. The fruit-of-the-Spirit language in Galatians and the ladder of virtues in 2 Peter both assume that character is cultivated, not achieved in a single act of willpower. These verses invite readers to look inward first, with what Wright calls sorrow and fear rather than pride, and then to get to work.
What scholars say
Commenting on the vice list in 2 Peter, N.T. Wright asks how we should read a catalogue of other people's sins—and answers that we should read it with sorrow rather than pride, since these tendencies are present in all of us. Self-control, on his account, is the work of holding them back: putting wrong desires to death and growing right ones in their place.
“With that, we are into a world every bit as murky as that of my new friend the judge. We ought to read this list, not with a self-righteous pride (‘Oh, yes, look at those wicked people! Not at all like us!’), but with appropriate sorrow and fear. These tendencies are present in all of us; the point of self-control is to keep them back, to crucify wrong desires and grow right ones in their place. Injustice; wild orgies; grossly enlarged sexual appetites: these are people who leave their stain, like a bad smell in the air, in any company they join (verse 13).”
What it means for you
Start by noticing where your reaction to other people's failures is quiet superiority. That instinct—"not at all like me"—is exactly what these verses warn against. Self-control begins with admitting that the appetites and impulses you see in others also live in you, perhaps in quieter forms.
Then treat self-control as practice, not performance. Pick one desire that consistently pulls you the wrong way and one habit you want to grow in its place—the two moves belong together. Proverbs' image of the wall is useful here: walls are built stone by stone, and maintained daily. Small, repeated choices are how the fruit grows.
In context
These verses come from different corners of Scripture but form a coherent picture. Galatians 5 contrasts the "works of the flesh" with the fruit of the Spirit, of which self-control is the final item. Second Peter 1 opens the letter with a chain of virtues to be added to faith, while chapter 2 turns to false teachers whose lives illustrate what happens when those virtues are abandoned—the vice list Wright comments on. Proverbs 25 sits within a collection of practical wisdom sayings, using vivid comparisons to describe a well-ordered life.
