Read Matthew 12.
Does it really matter what you say?
How often do we say things that are mean, unkind, and hurtful and then follow those words with, “I didn’t really mean it”?
How often do people use words that are crass, crude, rude, condescending, demeaning, and/or untruthful? But we give them (or ourselves) a pass by saying, “I/He was just letting off steam” or “S/he’s really a nice person but just has a temper.”
I think that many Christians today think sins of speech are less of a problem than other kinds of sin.
Jesus said otherwise. Words were very important to him because they reveal what is in a person’s heart.
“For the mouth speaks what the heart is full of. A good man brings good things out of the good stored up in him, and an evil man brings evil things out of the evil stored up in him” (vv. 34c-35).
In context, Jesus is addressing the sin of the Pharisees in saying that Jesus “drives out demons… by Beelzebul, the prince of demons” (v. 24). In our culture, someone who heard that might say, “They’re just jealous” or give some other excuse for what the Pharisees said.
To Jesus, however, the way the Pharisees tried to explain away Jesus’s miracles was a statement of faith, an expression of their beliefs about Jesus. Or, rather, their unbelief about who Jesus is.
Words are not empty in God’s sight at all. They are the basis on which either you will be acquitted or condemned when you stand before God in judgment (vv. 36-37). Evil words, untruthful words, harsh words, unkind or unbelieving words all reveal what you really think, the ideas that you mull over in your heart. Your words and mine let us see inside the mind; they reveal what conclusions you’ve come to in your heart. They show what is important and valuable to you. They demonstrate how little (or much) you value God and other people.
Each human being with will be judged by his or her words. Yet Jesus’s prescription for an evil mouth was not to watch what you say.
Instead, Jesus said, “Make a tree good and its fruit will be good” (v. 33a). Since what you say comes from your heart, the only way to clean up your speech is to cleanse your heart.
Jesus came not only to atone for and forgive our sins of speech; he also came to change our hearts so that the words we speak are true, kind, loving, gentle, and good. As you grow in your faith in Christ, your words should reflect it.
How are your speech patterns? Do your words fit with your profession of faith as a Christian or do they reveal a heart that is filled with–or still struggling with sin?
Ask God for the grace to speak words that are pleasing to him. Ask him to help you grow and to cleanse your heart so that whether a believer or an unbeliever speaks with you, he will see the life-transforming work that God’s Holy Spirit is doing in your life.
And, fill your heart with good things, with godly truth and the word of God itself. As your heart is purified, your words will be better for, “the mouth speaks what the heart is full of” (v. 34).
One more thing: Some of the most powerful words in the English language are, “I’m sorry. Will you forgive me for what I said to you and/or about you?” Is there someone you need to say those words to today?
