Is Sin Really Real?
Month 6: The Cross — Why Jesus Died · Why We Believe
Today's Scripture
Read together: Romans 3:10-12, 19
10 As it is written: “There is no one righteous, not even one. 11 There is no one who understands, no one who seeks God. 12 All have turned away, they have together become worthless; there is no one who does good, not even one.” … 19 Now we know that whatever the law says, it says to those who are under the law, so that every mouth may be silenced and the whole world held accountable to God.
Memory Verse
“for all have sinned and fall short of the glory of God,”— Romans 3:23 (BSB)
📖 Bible-in-a-Year (optional)
Today's reading: 1 Kings 3–4; 2 Chronicles 1
Reading the whole Bible in a year — do this when you have extra time. (Around Day 153 of 365 — young King Solomon asks God for wisdom.)The Heart of It
Our world often says there's no such thing as sin. It says there are only mistakes, or bad choices, or simply "doing what feels right for you." But paints a different picture, and it does it bluntly. It says, "There is no one righteous, not even one… there is no one who does good, not even one" (vv. 10, 12). Paul stacks up Old Testament quotes like bricks to make one point. Sin isn't just a few bad actions on the outside. It's a condition we're all born with on the inside. It's not that humans are as bad as they could possibly be. It's that sin touches all of us, in every part.
Verse 19 says this leaves the whole world "held accountable to God." Why? Because the standard isn't comparing ourselves to each other. The standard is God's perfect holiness. If we only measure ourselves against other people, we can always find someone worse and feel okay. But God's law is like a mirror. It doesn't clean your face. It just shows you the dirt is real (). And here's the kindness in it. God doesn't show us the problem to shame us. He shows it to send us running to the cure. You won't reach for a doctor until you believe you're sick. Sin is real, and so is the Savior.
Around the Table
Sometimes our hearts want to do wrong things, even when no one is watching. That's real. But Jesus can change our hearts.
Let's do it: Look in a mirror. A mirror shows your face, but it can't wash it. Only Jesus can wash our hearts clean.
Some people say sin isn't real. But the Bible says everyone falls short. And we know it's true when we're honest about our own hearts.
Let's talk: Why is it easier to notice other people's sin than our own?
God's law is like a mirror. It shows us the problem, but it can't fix it. That's why we need a Savior, not just better behavior.
Let's go deeper: How would you kindly answer a friend who says, "I'm a good person; I don't need saving"?
💬 Conversation Starter
If sin weren't real, why does the whole world need police, locks, courts, and the word "sorry"? Everyone lives like right and wrong are real. That's because they are.
🛡️ Defending the Faith
When someone says, "Sin is just an old-fashioned idea. People are basically good": kindly point out something simple. No one has to teach a child to lie or to grab. Those come naturally. It's kindness that we have to teach. And every human culture, in every age, builds rules against the same evils. That shared sense of "ought" points to a real moral law. And a real moral law points to a real Lawgiver (). Always answer with gentleness and respect ().
For Dad · Go Deeper
Our culture has not deleted the idea of sin. It has only relocated it. People still feel deep guilt and outrage. They've just lost the framework that explains it, and the cross that resolves it. So they're left endlessly trying to feel clean by being on the "right side." gives your kids something far healthier. It gives them an honest diagnosis and a real cure. Don't soften verse 12 to make the family feel better. The bad news is what makes grace amazing. But always pair the mirror with the mercy. The goal isn't kids who feel worthless. It's kids who know they're sinners who are loved enough to be rescued. That's the most stable identity a child can have.

Let's Pray Together
"Father, thank You for being honest with us about sin. You don't pretend it isn't there. When we look at Your Word, we see that we need You. Thank You for showing us the problem, and for giving us the cure. Thank You for Jesus. In Jesus' name, amen."
Sin is real. And a God who tells us the truth about it is a God kind enough to save us from it.
