Every Single Person Has Sinned
(Romans 3:9-20)

The apostle Paul sat down to write a letter to the Christians in Rome. He had never visited them before, but he wanted them to understand a very important truth. Paul had been a teacher of God's law for many years. He knew the law inside and out. But something had changed his life completely. Paul had met Jesus on the road to Damascus, and now he knew that following the law could never save anyone. Only Jesus could do that.

Paul wrote, "What shall we conclude then? Are we any better?" He was asking about the Jewish people and the Gentiles - that means everyone who was not Jewish. Some people thought that being born a Jew made them special to God. Others thought that Gentiles were hopeless sinners. But Paul said something surprising. He said that both Jews and Gentiles are all under sin. Every single person has sinned. No one is better than anyone else when it comes to sin.

Paul went on to quote from the Old Testament, the holy writings that God had given to His people long ago. He pulled together verses from Psalms and Isaiah to make his point clear. He wrote, "There is no one righteous, not even one." Righteous means being perfectly good and right in God's eyes. Paul said that no one understands God on their own. No one seeks after God. Everyone has turned away from God. Together, all people have become worthless. There is no one who does good, not even one person.

Paul did not stop there. He kept piling up evidence from the Scriptures. He quoted verses about the mouth, the tongue, and the feet. He wrote that people's tongues practice deceit - that means they tell lies. Their mouths are full of cursing and bitterness. Their feet are quick to rush into violence and shed blood. Wherever they go, they leave behind ruin and misery. They do not know the way of peace. And worst of all, there is no fear of God before their eyes. That means they do not show respect or awe for the Creator of the universe.

Paul was painting a picture of the whole human race. Every person - from the most religious to the most rebellious - has sinned against God. No one can stand before God and say, "I have always been good." The evidence from the Old Testament was clear. All people are guilty. The prophet Isaiah had written hundreds of years earlier that all of us have gone astray. King David had written in the Psalms that no one does good. Paul was showing that this was not a new problem. It had been true from the very beginning.

Then Paul explained something that might sound strange at first. He said that the law - the rules God gave to Moses on Mount Sinai - was not meant to make people righteous. That was never its purpose. The law was given to make people conscious of their sin. Think of it like a mirror. When you look in a mirror, you see dirt on your face. The mirror does not clean your face. It just shows you that you are dirty. In the same way, the law shows us our sin. It helps us see that we have broken God's commands. But the law cannot wash away our sin. It cannot make us clean. It only points out that we need to be washed.

Paul wanted the Romans to understand that no one will be declared righteous by observing the law. The law was like a teacher that points to a problem. The problem is that every single person has sinned and falls short of God's glory. No one can fix that problem on their own. The law makes us aware of our sin so that we will look for someone who can save us. And that someone is Jesus Christ. He came to do what the law could never do. He lived a perfect, sinless life and then died on the cross to take the punishment for our sins. He rose from the dead to give us new life. The law shows us our need. Jesus meets our need.

So Paul's message to the Romans was clear and simple. All people have sinned. No one is righteous on their own. The law shows us our sin but cannot save us. Only Jesus can save us. That is the good news of the gospel. We all need a Savior, and Jesus is that Savior.

A Curious Question

Why did God give us the law when He knew we could never perfectly follow it?

Old Testament Connection

In Romans 3, Paul quotes from several Old Testament books including Psalms and Isaiah. These verses were written hundreds of years before Jesus was born, yet they already described the sinful condition of every person. God used the Old Testament prophets and poets to show that all people need a Savior. The law was given to Moses on Mount Sinai as part of the Old Covenant, but its purpose was never to save anyone. Instead, the law was like a spotlight shining into the dark corners of our hearts. It reveals our sin and shows us that we cannot fix ourselves. This points forward to Jesus, the only one who could keep the law perfectly. Jesus fulfilled the law by living a sinless life and then died in our place. The Old Testament law shows us our sickness, and Jesus is the cure. Every Old Testament sacrifice and every commandment was a shadow pointing to the perfect sacrifice of Christ on the cross.

Discussion Questions

  1. Paul said that no one is righteous, not even one. What do you think it means to be righteous, and why can't anyone become righteous on their own?
  2. Paul compared the law to a mirror that shows us our sin. How is the law like a mirror, and what does it show us about ourselves?
  3. If the law cannot save us and only shows us our sin, why do you think God still gave it to His people in the Old Testament?

So What? What Can I Do?

  • Admit your need. Have you ever thought you were good enough on your own? This passage shows us that no one is. When you sin, tell God honestly that you need His forgiveness. You do not have to pretend to be perfect. God already knows everything, and He loves you anyway.
  • Thank God for the law. The law shows us our sin, and that might feel bad at first. But it is actually a gift because it points us to Jesus. Thank God for giving us the law so we can see our need for a Savior.
  • Trust Jesus alone. You cannot earn your way to heaven by being good or following rules. Only Jesus can save you. Trust in what He did on the cross and believe that He rose from the dead. Ask Him to be your Savior today.

Memorize God's Word

Romans 3:23 - "For all have sinned and fall short of the glory of God."

• For all have sinned hold out your hands with palms up to include everyone in the room.

and fall short lower your hands from high to low as if you are missing a target.

of the glory point upward with both index fingers toward heaven.

of God point both hands upward toward the sky.

Praying with Kids

Dear Father, we thank You that even though all of us have sinned and fallen short of Your glory, You did not leave us alone. Thank You for giving us the law to show us our sin and for sending Jesus to save us. Help us to trust in Jesus every day and to share His love with others. In Jesus' name, amen.

Craft or Activity

Mirror of the Law Craft

How to Make the Mirror of the Law:

  1. Cut a piece of cardstock into a shape that looks like a mirror frame, such as a rectangle or an oval with a hole in the middle.
  2. Cut a piece of aluminum foil slightly larger than the hole in the frame.
  3. Glue the aluminum foil behind the hole so it creates a shiny mirror surface.
  4. Decorate the frame with markers or crayons.
  5. Write on the frame the words, "The law shows me my sin. Jesus cleans me."
  6. Use the mirror to remind you that the law shows us our need for Jesus.

Effective Teaching Techniques

For Younger Children: Focus on the simple truth that everyone has done wrong things and needs Jesus. Use the mirror illustration and let each child look at their reflection and then talk about how a mirror cannot clean them, just like the law cannot save them.

Prep Shortcut: Pre-cut the cardstock shapes and the foil squares before class so children can focus on decorating and writing the verse. This saves time and keeps little hands busy with the fun parts.

Classroom Management: When discussing sin, keep the tone gentle and hopeful. Remind children that God loves them and that Jesus is the answer to our sin problem. Celebrate that we do not have to be perfect because Jesus was perfect for us.

For Older Kids: Challenge them to look up the Old Testament verses Paul quoted in Romans 3:10-18. Have them read the original context in Psalms and Isaiah and discuss how those verses already pointed to the universal problem of sin.
