Matthew 15:18-20
“But the things which proceed out of the mouth come out of the heart, and they defile the man. For out of the heart come evil thoughts, murders, adulteries, sexual sins, thefts, false testimony, and blasphemies. These are the things which defile the man; but to eat with unwashed hands doesn’t defile the man.””

Title: What Really Makes You Unclean
Scripture: Matthew 15:18-20
Jesus just finished telling the Pharisees that handwashing can't defile anyone. Now he tells his disciples what actually defiles a person. It's not dirty hands that make you unclean. It's the filth that comes out of your heart.
The Pharisees obsessed over external purity. They washed cups, pots, and hands. They avoided certain people and places. But Jesus cuts through all that. He says what comes out of your mouth reveals what's in your heart. Your words expose you.
This should make us stop and think. We worry about looking good to others. We clean up our appearance, watch our manners, post the right things online. But Jesus says that's not where the real problem lies. The real problem is inside, where others can't see.
Look at his list: evil thoughts, murder, adultery, sexual immorality, theft, false testimony, slander. These start in the heart before they become actions. You don't just commit adultery. You think about it first. You don't just murder. You harbor hatred first. The heart is the factory where sin gets made.
This means you can't fix yourself by trying harder. You need a new heart. You need Jesus to cleanse you from the inside out. That's what the gospel offers. Not just forgiveness for sins you've done, but transformation for the heart that produces those sins.
So stop worrying so much about looking religious. Start asking God to show you what's in your heart. When you catch yourself thinking evil thoughts, confess them immediately. When you're about to speak harsh words, remember they reveal your heart's condition. Pray daily for God to cleanse your heart and make it new.
Prayer: Lord, we confess that we're often more concerned with how we look than with what's in our hearts. Show us the evil thoughts and desires we hide from others. Cleanse us from the inside out through the blood of Christ. Create in us clean hearts that love you and love our neighbors. Amen.
