“Don’t you see that whatever enters the mouth goes into the stomach and then out of the body? But the things that come out of a person’s mouth come from the heart, and these defile them. For out of the heart come evil thoughts—murder, adultery, sexual immorality, theft, false testimony, slander. These are what defile a person; but eating with unwashed hands does not defile them.”Matthew 15:17-20
The Pharisees had the wrong understanding of what made a person “unclean.” They were hung up on traditions made by men that tried to keep people ritually clean through external purity. One of those traditions was to wash hands before eating so that the “uncleanness” from any Gentile item, dead or unclean animal that was touched in the marketplace would be washed away and not contaminate the food that was about to be eaten.
But Jesus clarifies to His own disciples that “cleanness” isn’t about what goes into one’s stomach, but what comes out of one’s heart. And one of the easiest ways to determine what is in our own hearts is to listen to what we say and how we say it.
It’s easy enough to flex our religious muscles and makes sure we sound holy around certain people. But when we are pressed in life, what comes out of our mouth then?
When we squeeze an orange, we expect orange juice to come out. When we press an olive, we expect olive oil to come out. What a peculiar sight it would be to squeeze a lemon and have motor oil come out. How strange it would be to press a cluster of grapes and have corrosive bleach leak out.
Yet, what Jesus is saying is that this is how we discover the broken places in our own hearts. This is exactly what happens to us. Evil thoughts come from the heart. Murderous rage comes from the heart. The roaming eye of adultery comes from the heart. The need to find acceptance and love by giving away our body to many different people through sexual immorality comes from the heart. The compulsion to take what is not ours comes from the heart. The tendency to lie, deceive, gossip, and slander comes from the heart. Harsh and critical words come from the heart.
When a Christian is pressed or squeezed by life circumstances, we should expect the fruit of the Spirit to come leaking out: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control. If we get pressed by life and something else comes out of our heart, we need to see it like a warning light on the dashboard of our life. Something is broken in the deep places of our soul. Something in our heart needs healing.
So, what comes out of your mouth when life squeezes you? Pay attention to anything unclean that comes up. Use it as a diagnostic tool to understand that this is a place in your heart that needs healing. Our damaging and destructive words, our foul language, our bitter gossip and biting criticism are all products of a heart that needs healed by the love of God.
