Is Sin Really a Big Deal? A Louisville Pastor's Take on Why We've Stopped Calling Sin "Sin"

Lyndon Christian Church | Louisville, KY

If you've ever wondered what the Bible actually says about sin, or found yourself asking is sin really that serious, you're not alone — it's one of the most common questions people bring to church here in the Lyndon area of Louisville, Kentucky.

Here's a modern-day example. WNBA guard Sophie Cunningham recently drew national backlash for saying she wanted to protect girls in sports and locker rooms from having to compete against biological men. She wasn't hostile. She said she loved everyone, but insisted that love and truth belong together. That's a biblical combination: conviction plus love is what Scripture calls righteousness. Yet culture treated her stance as the wrongdoing.

Meanwhile, our culture routinely celebrates what the Bible calls sin. Jordan Belfort, the real-life "Wolf of Wall Street," is now booked as a media commentator on ethics. Feuding rappers are praised as "savage" for public humiliation instead of practicing forgiveness. Muhammad Ali's career leaned heavily on self-promotion, which we relabel as "confidence." Politicians' broken promises get excused as "4D chess." We've gotten remarkably good at calling evil good and good evil — and remarkably good at renaming sin: an "error in judgment," a "learning opportunity," "just part of the journey."

This isn't a new problem. 

In the first century, Gnosticism taught that the spiritual self was all that mattered and the body's actions were irrelevant — so sin became something to explain away rather than repent of. The apostle John confronted this directly: "If we say we have no sin, we deceive ourselves, and the truth is not in us" (1 John 1:8). Sound familiar? Swap "true self" for "authentic identity," and it's the same lie in new packaging.

Scripture actually uses six different Greek words for sin — missing the mark (Paul, at Romans 3:23), crossing a boundary, trespassing onto forbidden ground, lawlessness (John, at 1 John 3:4), a debt owed (at Matthew 6:12), and ungodliness, a posture of living as though God doesn't exist (at Romans 1:18). Together, they paint sin as far more than an "oops."

So why does taking sin seriously still matter, even after you're forgiven?

A few reasons: it gives you an accurate view of the cross, it changes how you live, it produces deeper love (Luke 7:47 — the person forgiven much, loves much), it reminds you that sin's consequences don't vanish just because you've been forgiven, and it equips you to actually help people who are drowning in shame instead of just telling them "everybody makes mistakes."
