“But those things which proceed out of the mouth come from the heart, and they defile a man.” Matthew 15:18
The Bible stresses that what you say is an accurate indicator of what is in your heart. If your words bless and encourage others, they give evidence of a compassionate heart. If you often share the good news about Christ, you demonstrate a heart that is grateful for your own salvation.
When others are in a crisis, do they know they will find peace and comfort in your words? Do you frequently and spontaneously offer prayers for others? Do your words and the manner in which you say them reveal a patient heart? All of these behaviors indicate a heart that is like the heart of the Father. Or do you often regret your words? Are there people even now who are hurt or angry because of something you have said? Do you enjoy gossip? Do you tend to criticize others? Do you feel that you are not responsible for what comes out of your mouth when you are angry? Does your mouth spew grumbling and complaints?
These behaviors come from a heart that is unlike God’s heart. You may say, “Oh, but that’s just the way I am! I’m always saying the wrong thing!” Yet Scripture clearly states that an abusive tongue is not under the control of the Spirit (James 3:3-10). A sanctified mouth is a wonderful instrument for the Lord. A heart like the Father’s heart will produce only pure and loving words. Without making any excuses for your words, ask the Holy Spirit to forgive you for any words that have brought harm. Then ask Him to discipline your mouth so that every word you speak is used by God to encourage and edify others.
