Matthew 12:34 says, “Out of the overflow of the heart the mouth speaks.” You can find out what’s really going on in your heart—your soul—by listening to the things you talk about most and by listening to how you talk about others.
One day, two men saw a woman walking down the road. One of the men said, “That’s Mrs. Jones. She always has something good to say about everyone.” The other man decided to test her, so when she got close he hollered, “Mrs. Jones, what do you think about the devil?” She thought for a second and answered, “He sure is busy, isn’t he?”
What if a recording of your conversations was running all week long at home, at work, at school, on the phone, and in your casual moments? Jesus says, as read in Matthew 12:35, “The good man brings good things out of the good stored up in him, and the evil man brings evil things out of the evil stored up in him.” This means that what you store up in your soul is what can come out of your mouth.
Everything that comes out of our mouth is painting a portrait of who we really are. Out of the abundance of the heart, the mouth speaks. If you’ve got corruption on the inside, corruption will come out on the outside. If you have a heart seeking the purity and righteousness of Christ, your words will express that to others.
Jesus taught us that our lives should be full of two loves: “Love the Lord your God with all your heart, soul, mind and strength.” And, “Love your neighbor as yourself.” (Matthew 22:37-40) When we live in obedience to those two great commandments, then our conversation would be mostly about Jesus and the needs of other people.
If you don’t like the output of your mouth, change the input to your heart. Load up on input that’s about loving Jesus and loving others. Then the recording will start to change because your heart is changing.
When our hearts are full of the love of God, our speech will be spreading His love and His forgiveness to others.
David prayed, “May the words of my mouth and the meditation of my heart be pleasing in Your sight, O Lord.” Psalm 19:14
