What does the Bible say about using foul language or making inappropriate jokes?

The Bible speaks clearly and thoughtfully about the use of language, including the use of foul language and inappropriate jokes. As a non-denominational Christian pastor, I would like to explore this topic in depth, considering both the direct scriptural teachings and the broader principles that guide our speech as followers of Christ.

First and foremost, the Bible emphasizes the power and importance of our words. Proverbs 18:21 states, "The tongue has the power of life and death, and those who love it will eat its fruit." This verse underscores the profound impact that our words can have, either for good or for harm. As Christians, we are called to use our speech to build up, encourage, and bless others, rather than to tear down or demean.

One of the most direct passages addressing foul language and inappropriate jokes is found in Ephesians 4:29, where the Apostle Paul writes, "Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up according to their needs, that it may benefit those who listen." Here, Paul instructs believers to avoid "unwholesome talk," which can be understood to include foul language, crude jokes, and any speech that is not edifying. Instead, our words should be constructive and beneficial to those who hear them.

Further reinforcing this idea, Paul writes in Ephesians 5:3-4, "But among you there must not be even a hint of sexual immorality, or of any kind of impurity, or of greed, because these are improper for God's holy people. Nor should there be obscenity, foolish talk or coarse joking, which are out of place, but rather thanksgiving." In this passage, Paul explicitly mentions "obscenity, foolish talk, or coarse joking" as behaviors that are "out of place" for Christians. Instead of engaging in such speech, we are encouraged to cultivate a spirit of thankfulness.

The teachings of Jesus also provide profound insight into the importance of our words. In Matthew 12:36-37, Jesus says, "But I tell you that everyone will have to give account on the day of judgment for every empty word they have spoken. For by your words you will be acquitted, and by your words you will be condemned." This sobering reminder highlights the accountability we have for our speech and the seriousness with which we should approach the words we use.

Additionally, James 3:5-10 offers a vivid metaphor for the power of the tongue, comparing it to a small spark that can set a great forest on fire. James writes, "The tongue also is a fire, a world of evil among the parts of the body. It corrupts the whole body, sets the whole course of one's life on fire, and is itself set on fire by hell. All kinds of animals, birds, reptiles and sea creatures are being tamed and have been tamed by mankind, but no human being can tame the tongue. It is a restless evil, full of deadly poison. With the tongue we praise our Lord and Father, and with it we curse human beings, who have been made in God's likeness. Out of the same mouth come praise and cursing. My brothers and sisters, this should not be." James emphasizes the inherent contradiction in using our tongues for both blessing and cursing, and he calls believers to a higher standard of speech.

In considering these scriptural teachings, it becomes evident that the Bible calls us to a standard of purity and integrity in our speech. Foul language, crude jokes, and inappropriate comments are not merely harmless or trivial; they reflect the condition of our hearts and can have significant consequences for ourselves and others.

Moreover, the principle of loving our neighbors as ourselves, as commanded by Jesus in Matthew 22:39, should guide our speech. When we use foul language or make inappropriate jokes, we risk demeaning, hurting, or offending others. Instead, our words should reflect the love and respect we are called to show to every person, recognizing their inherent dignity as beings made in the image of God.

Christian literature also offers valuable insights into the importance of our speech. In his book "The Pursuit of Holiness," Jerry Bridges writes, "We must learn to speak the truth in love, to build up others with our words rather than tear them down, and to avoid all forms of unwholesome talk." Bridges emphasizes the necessity of aligning our speech with our commitment to holiness and the call to edify others.

Similarly, in "Mere Christianity," C.S. Lewis discusses the moral implications of our words. He notes, "The sins of the tongue are not only among the most common but also among the most destructive. They can ruin relationships, damage reputations, and sow discord among believers." Lewis's observations remind us of the far-reaching impact of our speech and the importance of exercising wisdom and restraint in our language.

In practical terms, cultivating godly speech requires intentionality and self-discipline. It involves being mindful of the words we use, avoiding situations where we are tempted to engage in inappropriate talk, and seeking accountability from fellow believers. Prayer is also essential, as we ask God to purify our hearts and guide our speech. Psalm 19:14 offers a beautiful prayer in this regard: "May these words of my mouth and this meditation of my heart be pleasing in your sight, Lord, my Rock and my Redeemer."

In conclusion, the Bible provides clear and compelling guidance on the use of language, calling believers to avoid foul language and inappropriate jokes. Our speech should be characterized by purity, edification, and love, reflecting the transformative work of Christ in our hearts. By aligning our words with the principles of Scripture, we honor God and build up those around us, fulfilling our calling as His ambassadors in the world.
