Many sincere believers quietly carry guilt about the mortgage, car loan, or student loan they owe. Somewhere along the way they’ve absorbed the idea that debt is sin—that faithful Christians should owe nothing to anyone. Ever. Often the conviction rests on a single Bible verse they’ve read or heard in a sermon. So it is worth asking: does the Bible actually teach being in debt is sin?
The short answer: no, but with important qualifications. Scripture treats debt not as something forbidden in itself—like idolatry or adultery—but as a matter of wisdom and the heart. It doesn’t command, “You shall not borrow.” Instead, it regulates borrowing, warns about it soberly, and exposes the conditions that turn debt into bondage or sin.
What the Bible Actually Does With Debt
The clearest sign borrowing isn’t inherently sinful is this: God’s own law assumes and governs it. The law of Moses built in a seventh-year release of debts (Deuteronomy 15). It commanded God’s people to keep giving generously lending to the poor even as the release year approached—and the loans were less likely to be paid. It forbade charging interest to poor fellow Israelites (Exodus 22:25; Leviticus 25:35–37). Merciful regulations such as these would make no sense if borrowing were wicked in itself. Jesus, too, simply assumes lending does happen and commands generosity within it (Matthew 5:42; Luke 6:34–35). The Bible’s posture toward debt is regulation and mercy, not prohibition.
Sure, some passages are sometimes read as prohibitions. Deuteronomy 28:12 lists “you shall lend to many nations and shall not borrow” as a covenant blessing, and 28:44 lists perpetual borrowing among the curses for disobedience. But this is the language of national covenant. In other words, this passage is about national prosperity or ruin; it describes how a faithful Israel would flourish and how a rebellious one would decline. It isn’t a private rule declaring every personal borrowing to be a mark of God’s displeasure.
The Verse Everyone Quotes
The text behind most “debt is sin” teaching is Romans 13:8: “Owe no one anything, except to love each other.” Read alone, it does sound like a flat ban on debt. But the surrounding context is about meeting obligations. The previous verse says, “Pay to all what is owed… taxes… revenue… respect… honour.” Paul’s concern is that Christians should faithfully discharge what they owe: and the one debt that’s never fully paid off is the ongoing debt of love we owe one another.
This is how the great interpreters have understood it. John Calvin took Paul to be requiring that debts be repaid, not forbidding borrowing altogether. The same reading runs through Charles Hodge and John Murray, and more recent commentators such as Douglas Moo and Thomas Schreiner agree: Paul isn’t outlawing credit. Instead, he is commanding integrity in our obligations, while lifting up love as the one debt that always remains outstanding. The verse tells us to stay current on our obligations—not to avoid ever taking an obligation on.
The Warnings We’re to Heed
If borrowing is permitted, it’s far from risk-free, and Scripture says so plainly. “The borrower is the slave of the lender” (Proverbs 22:7). This is wisdom—sober observation rather than command—and it names a real danger: debt hands a measure of our freedom to someone else. For Christians whose lives are meant to be freely available for service and generosity, that loss of liberty is a genuine cost to weigh.
A second proverb pinpoints where the sin actually lies. “The wicked borrows but does not pay back, but the righteous is generous and gives” (Psalm 37:21). Notice here too: the sin isn’t in the borrowing but in our negligence to repay. Walking away from a debt we could honour, treating obligations casually, borrowing with no realistic intention or ability to pay—that’s a form of broken faith, and it offends the eighth commandment, which requires honesty and faithfulness in all our dealings. Two people may carry the very same loan; the one who repays faithfully and the one who defaults wilfully stand in entirely different places before God.
When Debt Becomes Sin
Because debt is a matter of the heart, the same loan can be righteous in one person and sinful in another. Debt becomes sin when it grows from a corrupted root.
- It becomes sin when it springs from covetousness — borrowing to fund possessions or a lifestyle that discontentment, not need, demands (Hebrews 13:5).
- It becomes sin through presumption about the future, the very attitude James rebukes when he warns against boasting of tomorrow’s profits as though our days were in our own hands (James 4:13–16).
- It becomes sin when it expresses an idolatry of security or status, using credit to manufacture, control or to keep up appearances—a quiet unbelief in God’s provision (Matthew 6:25–34).
- And it becomes sin through plain poor stewardship, since we’re accountable for how we manage what God entrusts to us (Matthew 25:14–30).
So two families may hold identical mortgages—one in faith, prudence, and thanksgiving, the other in covetous presumption. The debt is the same; the spiritual condition, however, is the opposite.
When Borrowing Can Be Wise
The flip side is that some borrowing can be a legitimate, even wise, act of stewardship: a mortgage on a needed home, sound investment in a business, or training that increases one’s ability to provide. Jesus Himself commends counting the cost before building (Luke 14:28). Many find it helpful to distinguish productive debt—which serves genuine provision, from consumer debt, which merely feeds appetite. Scripture gives us principles rather than a formula, and calls each believer to judge soberly before God whether a particular debt serves faithful stewardship. Or simply feeds discontent.
The Heart of the Matter
There is a deeper layer here we dare not miss. The Bible’s master picture of sin is debt. We pray, “Forgive us our debts” (Matthew 6:12). Jesus tells of a servant forgiven an unpayable fortune (Matthew 18:23–35). Paul says the record of debt that stood against us was nailed to the cross (Colossians 2:14). Every Christian is someone who owed God an infinite debt, could never repay a fraction of it, and has had the entire account cancelled in Christ.
That reality transforms how the forgiven handle money. It makes us scrupulous about what we owe others, because we take obligation seriously. It makes us merciful toward those indebted to us, because we’ve been forgiven a debt that’s even greater. And it frees us from the love of money that drives sinful debt in the first place.
So, is it sin for Christians to be in debt? Not in itself. Debt becomes sin when it flows from covetousness, presumption, or discontent; when it is entered recklessly or never repaid; or when it so enslaves us that our freedom to serve and give to God is lost. The wise path is to count the cost soberly, repay faithfully, cultivate contentment that loosens debt’s grip, and rest in the God who has already cancelled the only debt that could ever have destroyed us.
Tough Questions, Honest Answers
Does Romans 13:8 forbid all debt?
No. The command “Owe no one anything” sits inside a passage about discharging obligations—the previous verse tells believers to pay taxes, revenue, respect, and honour to whom they are due. Paul is requiring that we keep current with what we owe, not that we never enter an obligation, and he adds that love is the one debt we can never finish paying. Calvin, Charles Hodge, John Murray, Douglas Moo, and Thomas Schreiner all read it this way. The verse forbids defaulting, not borrowing.
Is it sin to have a mortgage?
Not in itself. A mortgage on a home a family genuinely needs, taken on with a realistic plan to repay, can be a sound act of stewardship—the very thing Jesus pictures when He commends counting the cost before building (Luke 14:28). Sin enters only through the heart and the circumstances: borrowing far beyond our means, stretching for status rather than shelter, or presuming on a future God hasn’t promised. The same mortgage can be faithful for one family and reckless for another.
Is paying interest sinful?
No. A borrower who pays the interest he freely agreed to is simply honouring his contract, which is exactly what Scripture commends (Psalm 37:21). The Bible’s interest laws were aimed at protecting a poor brother from being crushed in his distress (Exodus 22:25; Leviticus 25:36–37), not at banning all interest everywhere. The wise concern is practical rather than moral: high-interest debt can quickly enslave us (Proverbs 22:7), so it should be approached with great caution.
Is it sinful to charge interest on a loan?
For much of church history many taught that all lending at interest was sin, leaning on the Old Testament laws. But those laws specifically targeted exploitation of the poor and desperate, not ordinary commercial lending. Calvin argued interest isn’t wrong in itself, provided it’s fair, doesn’t grind down the needy, and serves genuine mutual benefit. This is the position that has shaped centuries of Christian economic thought. The sin lies in predatory or exploitative lending, the kind Nehemiah confronted (Nehemiah 5), not in charging a just rate.
What does the Bible say about not repaying debt?
It treats willful default as a serious moral failure. Psalm 37:21 ties not paying back to wickedness, and the eighth commandment requires honesty and faithfulness in everything we owe our neighbour; the godly person keeps his word even when it costs him (Psalm 15:4). At the same time, Scripture shows real mercy toward those who genuinely cannot pay, building debt release into Israel’s law (Deuteronomy 15). So the sin is refusing to repay what you could — not honest inability handled with integrity.
Does the Bible warn against co-signing or guaranteeing someone else’s debt?
Yes, and surprisingly forcefully. Proverbs returns to this again and again, urging strong caution about “putting up security” for another person’s debt because it can drag us into a ruin we never created (Proverbs 6:1–5; 11:15; 17:18; 22:26–27). This isn’t an outright ban—helping others is good and commendable. But its sober wisdom warns us against binding our family’s future to obligations we cannot control. The counsel is to count the cost soberly and never pledge what we could not afford to lose.
Is it sinful for Christians to declare bankruptcy?
Not automatically, though it’s never to be treated lightly. Because Scripture takes repayment so seriously (Psalm 37:21), bankruptcy must never become a convenient escape from debts we can actually meet. Yet God Himself built lawful debt release into Israel’s life through the sabbatical release and the Jubilee (Deuteronomy 15; Leviticus 25), recognising that crushing, genuinely unpayable debt sometimes needs a merciful end. Used honestly as a last resort for real insolvency—rather than as a trick to shed duties while keeping assets—it can be a legitimate legal mercy. The heart question is whether we’re fleeing responsibility or facing true inability with integrity.
