Written on our hearts?

Lately, we’ve been talking about our God who creates. Today is about our God who relates to people. God has an unwritten law in nature that tells us about who he is and what he’s like. He also has a written law, which we call the Bible.

But we’re going to talk about another kind of law. God put his law in the heart of every human being. This is what theologians call the moral law, and it impacts everyone who has ever lived.

He actually put it in your DNA, and not just you, but he put it in the DNA of every human being. He wove it into the fabric of our first parents, Adam and Eve, and every descendant of Adam and Eve since then has this part of God’s law woven into their nature, or their DNA.

God’s moral law is really written on the hearts of people.

A few weeks ago, I told you how God’s written law was written with his own finger when he wrote out the 10 Commandments on tablets of stone and gave them to Moses. Well, the moral law was written on the hearts of people, and not just on the heart Christians, but on the heart of every person.

Memory Verse

The reason I can say this is because that’s exactly what the Bible teaches us in Romans chapter 2. This verse a little bit longer than the than the average memory verse we use, but I really want to ask you, would you do some hard work this week and memorize it? If you have children, will you help them memorize it?

What this verse is saying is really important. The guy who’s writing this passage in the Bible is himself a Jew, and he grew up learning about the written law of God. His mom and dad taught him the law, but he also grew up as a Pharisee, which means a teacher of the law. He grew up reading the law, studying it, memorizing it, and helping other people put it into practice.

Now he’s writing a letter to a group of people in a foreign land. They’re not all Jews, and he’s pointing out something about the people who didn’t grow up like him, which means their moms and dads didn’t teach them the Bible. They didn’t have a Bible to read when they were growing up. They just instinctively knew right and wrong, and their hearts taught them how to live.

What Paul, the guy who wrote this passage, is teaching us is that people all over the planet, even if they’ve never heard the name of Jesus and have never even seen a Bible, know the difference deep in their hearts between right and wrong.

And Paul is teaching us that the knowledge of right and wrong deep in their hearts actually came from God. It came from the way God created people in the first place when he made Adam and Eve in the Garden of Eden.

When God made those two, he made them into moral beings, able to understand the difference between right and wrong. The animals, the fish in the sea and birds of the sky, just instinctively do what their nature tells them to do, but they don’t understand the difference between right and wrong… not at all like you and I do.


Now, I want you and your friend or family to have an honest conversation about God’s moral law this week, and here’s how I’d like to guide your conversation:

Describe your heart to a friend or to your children. Then I want you to ask them to describe their heart to you. Ask the the question: Do you need to be told not to lie before you know instinctively that it’s wrong? Did you need your mom or dad to tell you, “Don’t steal,” before you knew that stealing was wrong?

Or did you already know it in your heart?
