Out of the Mouth

I’ve been reading through the book of Matthew this month, and you would be surprised at what I’m learning. I’m finding that this book of the Bible has much to teach me. And I must be open to learning these truths. Earlier this week, I read chapter 15 and wow! It says that whatever is in our heart is what comes out of our mouth.

Jesus gives us examples of the types of evil that are in our hearts that then spew from our mouths. Everything gets its start in our hearts. Here we go. Evil thoughts. Murder. Adultery. All sexual immorality. Theft. Lying. Slander. Greed. Wickedness. Deceit. Lustful desires. Envy. Pride. Foolishness. Just to name a few. Jesus says that these things defile us. That means we are polluted and unclean.

When we act and speak in sinful ways, the finger of guilt will point back to our heart. It’s because evil is in us. The words that come out of our mouth are sometimes well thought out. In other words, they are premeditated, the same as other acts of unkindness. But there are also words and acts that are spontaneous. Spur of the moment. Impulsive. And either way. If they’re premeditated or spontaneous, they still come from the heart.

But the words you speak come from the heart—that’s what defiles you. For from the heart come evil thoughts, murder, adultery, all sexual immorality, theft, lying, and slander. These are what defile you. Eating with unwashed hands will never defile you. Matthew 15:18-20

It is what comes from inside that defiles you. For from within, out of a person’s heart, come evil thoughts, sexual immorality, theft, murder, adultery, greed, wickedness, deceit, lustful desires, envy, slander, pride, and foolishness. All these vile things come from within; they are what defile you. Mark 7:20-23

The Lord observed the extent of human wickedness on the earth, and he saw that everything they thought or imagined was consistently and totally evil. So the Lord was sorry he had ever made them and put them on the earth. It broke his heart. Genesis 6:5-6

God knows that we’re only evil all the time. That was not his plan for us, but we have disregarded his truth and have charted our own paths. We live as if we are our own god. When God saw all the evil on the earth, he created a plan to clean it up and start over. He caused a flood to fill the earth. It destroyed every living and breathing thing. Animal and human. But before the flood, God had commanded Noah to build an ark. Once the ark was completed, every kind of animal walked onto the ark. Male and female. One of each. And Noah’s family. Noah, his wife, their three sons and wives. They were the only survivors. They were the start of a new people on the earth.

And yet. Here we are. Over time, the earth has once again filled with people. And wickedness abounds. I wonder if God is once again sorry that he put us on the earth.


It’s not what goes into your mouth that defiles you; you are defiled by the words that come out of your mouth. Matthew 15:11


I was driving home from the grocery store. For the past few weeks, one section of the road has been under construction. I’m not sure what type of work is being done, but it eventually closes down three lanes to two and then from two lanes to one. So, as you’re driving you have to continue moving into the next left lane. And then you find yourself and every other car in the only open lane.

So, of course, we all know what happens when there are lane closures. The people in the lanes that are closing have to move over, and those in the open lane have to make way for all these extra vehicles trying to squeeze in. Now the problem comes when people in the lanes that are closing wait until the very last second to merge into the open lanes. So when I turned left onto the road with construction, I remembered that the lanes ahead were closed. So I immediately got into the far left lane. That would mean I was in the only open lane until I turned at the upcoming light. I wouldn’t have to try to squeeze into a busy lane of traffic. But, of course, not all those coming behind me did as I did.

As we inched forward, we got past the first lane closure. Then up ahead, the second lane was closing. And, of course, up came a big vehicle wanting to get into my lane. This driver wanted to be in the exact spot I was in, and I couldn’t move. They waited until the very last second to try to move into the last open lane. And the car in front of me wasn’t allowing the vehicle into our lane. So, I begrudgingly thought to myself. I’ll let the vehicle in. So I waved him in. At the same time, here are the words I said in the safety of my car. Come on over, you idiot.

And then up came another car quickly trying to get into my lane. He would have moved ahead of me, if I would have allowed him the space. I decided no. I’m not letting a second car in. The car behind me can take their turn to let this bully car in. So I just continued on and didn’t allow the second car in.

Just as that happened, a parable in the Bible came to my memory. A father told his older son to work in the vineyard. He said no, but later felt guilty and went to do the work as his father asked. The father then told the younger son to work in the vineyard. The son said yes, but didn’t do it. Which son obeyed his father? The one who said no and did the work, or the one who said yes and didn’t work? The son who obeyed did so with a bad heart out of guilt. The other son was a liar.

You can read the parable in Matthew 21:28-32.

I found myself in a similar situation as those two sons. Which of my acts was worse? Pretending to be kind by letting the car in my lane, all the while saying unkind words with a bad attitude? Or not letting the next car in? Sure, I let the first driver in, but in my heart I was letting him know that he should have waited his turn like the rest of us. At least I wasn’t putting on an act with the second car. That’s what I tell myself. Oh. We can usually find a way to justify our actions. But that doesn’t make the act any better. An ungodly act or word is still ungodly. Nothing will change that.

I don’t know why I always have to be the example of what not to do. Just a few moments before the incident, I had been praying and asking God to forgive me for being so human. I asked him to forgive me of my bad attitude and judgmental ways. And I’d hardly spoken those words when I acted like a fool. Of course, the other driver didn’t know that. But God did, because he saw my heart. He heard my words.

I have much to learn. You would think that I would be closer to perfection. The older I get, the more I realize how much I need a Savior. I realize how much I still have to learn. There is much work ahead for this heart of mine, in this lifelong quest to be like God. It’s a never ending struggle. It’s a never ending lesson to learn.

What can and should change is my heart. Repentance. Humbling myself before my Creator, who knows my thoughts and actions. He will forgive. He is willing to clean up my ungodly heart, if I will only ask him. And then I must change the way I act and speak. And it is possible to change. The desire to be godly has to replace the desire to be my own god.

And now, dear brothers and sisters, one final thing. Fix your thoughts on what is true, and honorable, and right, and pure, and lovely, and admirable. Think about things that are excellent and worthy of praise. Philippians 4:8
