Bible in 5: Mark 7 — What Defiles Comes From You
Mark 7:1-23 confronts the tradition of washings and shows that evil springs from the heart, not the plate.
Jesus dropped a line that still makes us uncomfortable: what defiles a person doesn't enter through the mouth. It comes out of the heart. The scene is in Mark 7:1-23, when a delegation of Pharisees and scribes came from Jerusalem to watch his steps, not to learn from him.
Their complaint wasn't against the law of Moses, but against the tradition of the elders. Some disciples ate without washing their hands, and that was enough for condemnation. Jesus responded with Isaiah 29:13 and with a case that hurt: Corban, that custom of declaring a possession dedicated to God to be free from supporting father or mother (Mark 7:11-13).
The problem isn't outside
"There is nothing outside a person that by going into him can defile him, but the things that come out of a person are what defile him." (Mark 7:15, ESV)
«God doesn't ask you for a coat of paint; he offers you a new heart by grace, in Christ.»
Jesus didn't lower holiness: he took it to its root. Washings and pure foods were signs of a deeper cleansing, one that no one can give themselves. Ezekiel had already announced it: "I will sprinkle clean water on you, and you shall be clean from all your uncleannesses" (Ezekiel 36:25, ESV). And Mark notes that Jesus said this "thus declaring all foods clean" (Mark 7:19, ESV).
God isn't impressed by the surface. He told Samuel: "For the Lord sees not as man sees... the Lord looks on the heart" (1 Samuel 16:7, ESV).
The list nobody wants to read
"For from within, out of the heart of man, come evil thoughts... envy, slander, pride, foolishness. All these evil things come from within, and they defile a person." (Mark 7:21-23, ESV)
That list isn't a catalog of extreme cases. It's a mirror. Jeremiah said it without sugarcoating: "The heart is deceitful above all things, and desperately sick; who can understand it?" (Jeremiah 17:9, ESV). If evil springs from within, no layer of external effort covers it. The way out isn't putting on makeup: it's being cleansed. Hebrews 9:14 points to the only water that reaches the conscience, and it isn't water: it's the blood of Christ.
A new heart, not a facade
You live before two audiences at once: your family and your church, and your followers, your chats and your feed. Building a showcase faith is easy. The verse in your story, showing up to service on time, the right playlist. Inside, envy when someone else does well, mocking a classmate in the private group, the little lie to your parents. Mark 7 says those aren't details: that defiles you, and it comes from you. God doesn't ask you for a coat of paint; he offers you a new heart by grace, in Christ, and from there he reorders what's outside.
One step for this week. Open your phone and reread the last thing you wrote in your chats. Look at what kind of person shows up there, without filters. Bring that to God just as it is, with names and no excuses, and ask him for a clean heart. And watch out for the Pharisees' trap: there are customs in your church or your culture that aren't the gospel, and there are clear commands of God that we sometimes cover with comfortable traditions. The standard isn't what your group does, but what the Word says.
If no one saw your stories or heard you sing on Sunday, and only what comes out of your heart when no one is watching remained, what would appear? Are you cleaning the facade or have you asked Christ for a new heart?
