Matthew 15:18
Saturday, 27 December 2025
But those things which proceed out of the mouth come from the heart, and they defile a man. Matthew 15:18
“And those proceeding from the mouth, it comes from the heart, and those, it commonizes the man” (CG).
In the previous verse, Jesus gave the disciples a lesson in basic human physiology, something they should have thought through by themselves. Now, He uses that instruction to provide an example of what defiles a man, something foods do not do. He begins with, “And those proceeding from the mouth.”
Jesus turns the thought around. “Proceeding from the mouth” corresponds to “into the john it ejects.” Therefore, the source of what He is referring to will be different than the previous example. That is stated in the next words, “it comes from the heart.”
The meaning is that what enters the mouth is something external. It passes through the body and then is ejected. There was nothing defiling in the process. However, that which proceeds from the mouth, meaning that the words of man, come from within the man. Their source is the heart.
Remember that the heart in the Bible does not refer to the organ that pumps blood. It is only used figuratively for the place where moral preferences are derived. It is the biblical source of thoughts and feelings, of which Jesus next says, “and those, it commonizes the man.”
Here is a new word, koinoó, to make (or consider) profane. Thus, it is that which treats what is sacred as common or ordinary. To get the meaning, the adjective form is used this way in Acts 2 –
“Now all who believed were together, and had all things in common [koinos], 45 and sold their possessions and goods, and divided them among all, as anyone had need.”
People are to be sacred, having been made in the image of God. However, man becomes commonized through what comes from his heart and the words that proceed from his mouth. Jesus will explain why this is so in the next two verses.
Life application: The heart is the inventor of wickedness in man. This is then turned into action as he is spurred on by what the heart has developed. As noted, Jesus will explain the various ways that this occurs. However, we can already consider how this process is realized in us.
The things we think are often not things we would actually act on. Further, we would not normally say the thoughts that well up in us. We have filters and checks that properly suppress such things.
At times, however, the filters may be lacking. We blurt out something that is caustic, and it causes damage to a relationship. Even if it was unintentional, what we have said is perceived to be the reality of what is going on inside of us by the recipient of our words.
Likewise, the checks on our words and actions are usually in place to keep us from acting in certain ways. However, if we are hungry, that can exacerbate our mood in a negative way. We become hangry, releasing our anger because the normal checks are blocked through our physical degradation. This can be true with a lack of sleep, high-pressure situations, etc.
We are still accountable for our words and actions, but there are reasons they occurred. When it happens, we regret what we have done, showing that it wasn’t our intention to act in such ways. In an old Clint Eastwood movie, he said, “A man’s got to know his limitations.”
When we feel we are reaching a point where we may do wrong, we need to work harder at limiting the inclinations that arise. We may also want to remove ourselves from whatever situation we are in. This will keep us from saying or doing something we will later regret.
Everyone responds to internal and external stresses differently. Therefore, it is up to us to carefully monitor ourselves and respond to those things that stress us.
Having said that, there are people who have no such limitations. They openly act on their inappropriate impulses. The problem with this is that it can become ordinary as others follow suit. Pretty soon, you are in full San Francisco mode, where the majority of the people openly act out perversions, illegalities, and harmful conduct towards self and others.
Once this happens, the society is set in a doom loop that is very hard to rectify. This is why the whole world had to be destroyed by the flood. It is also why the whole world will once again be destroyed by fire. Be sure not to follow the world. Rather, be like Noah, who remained righteous in a world full of iniquity.
Lord God, give us wisdom in how we should deal with our weaknesses and limitations. We all have them, and we all need to carefully monitor ourselves when faced with pressures and stresses that weaken us. Be with us and help us to always be fixed on You and what You would want us to do. Amen.
