Why Do People Know Right From Wrong Without the Bible?

Have you ever wondered why an atheist gets angry when someone steals from him? Why does someone who's never opened a Bible still feel guilty when they lie?
The answer changes everything you thought you knew about judgment and morality.
The Unwritten Law You Can't Escape
In Romans 2:14-15, God reveals a stunning truth:
"For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves: Which shew the work of the law written in their hearts, their conscience also bearing witness..."
Did you catch that? God wrote His law on every human heart.
The Jews received the Ten Commandments on stone tablets. But what about everyone else? Are they off the hook?
Not even close.
Your Conscience Is the Witness
Think about this: You can tie a man to his bed, and he'll blame you for his inability to walk. That's external bondage with an external cause.
But nobody tied down your conscience. Nobody forced you to know right from wrong. That knowledge came pre-installed by your Creator.
This is why:
- Parents expect honesty from children (without teaching them lying is wrong first)
- Every culture has concepts of right and wrong
- You feel guilty when you do wrong—even in secret
- Children instinctively hide when they disobey
You know because God wrote it on your heart.
The Sobering Reality
Here's what terrifies people: "God shall judge the secrets of men by Jesus Christ" (Romans 2:16).
Every time you've done wrong and known it was wrong—that was your conscience bearing witness. You can't claim ignorance. You can't demand an exemption.
"For not the hearers of the law are just before God, but the doers of the law shall be justified" (Romans 2:13).
But here's the problem—you've broken that internal law. We all have. Even when you do good, if you're honest, your "good" had selfish motives.
The Only Solution
The law written on your heart wasn't meant to save you. It was meant to show you that you need saving.
You're not condemned because you broke the Ten Commandments. You're condemned because you're a sinner who has violated the very law God wrote on your heart—the one you can't deny knowing.
But here's the hope: "Knowing that a man is not justified by the works of the law, but by the faith of Jesus Christ" (Galatians 2:16).
Only Jesus can say, "Thy sins be forgiven thee." Only He can provide the righteousness you desperately need but could never earn.
Your Conscience Knows the Truth
Stop making excuses. Your conscience has been testifying all along. The question isn't whether you knew right from wrong—you did.
The question is: Will you stop running from the truth your heart already knows?
