Let no corrupt word proceed out of your mouth, but what is good for necessary edification, that it may impart grace to the hearers. (Ephesians 4:29, NKJV)
Acceptable profanity has reached an appalling level in America. Profane language is common place in the home and on the job. It is used in classrooms (from teachers as well as students), on social media, in popular music, movies, television and the internet. Just about everywhere someone is talking, profanity is given a place. Profanity adds nothing constructive to a conversation. Indeed, it distracts from it. Profane speech does not enhance clearer, more concise communication. It is spoken casually and mindlessly, as filler without context and without character. It is profoundly meaningless, useless and rotten (“corrupt”). Profanity does it “impart grace” to those who hear it, nor does it bring honor to the person who uses it. It disrespects God and shows contempt for others. Its companions are often anger and wrath (Eph. 4:31). Let us remember that our words show what is in our hearts. Jesus said that. And, He said our words will either justify or condemn us in the last day of judgment (Matt. 12:33-37). We must take great care to control our hearts, to control our tongues and avoid corrupt words.
3 But fornication and all uncleanness or covetousness, let it not even be named among you, as is fitting for saints; 4 neither filthiness, nor foolish talking, nor coarse jesting, which are not fitting, but rather giving of thanks. 5 For this you know, that no fornicator, unclean person, nor covetous man, who is an idolater, has any inheritance in the kingdom of Christ and God. (Ephesians 5:3–5, NKJV)
Continuing to warn against immorality, the apostle comes to “filthiness” in verse 4, which is indecency or nastiness. It particularly identifies communication that is obscene and shameful. That would certainly describe many (if not most) of the entertainment today, but it certainly is not limited to those venues. “Foolish talking” is silly buffoonery, stupid nonsense. Our words reveal our hearts. Therefore, our words should be kind and graced with thankfulness, not laced with vapid blather. “Coarse jesting” is crude jokes, rude and profane repartee, vulgar speech. The double entendre, that is designed to titillate with sexual innuendo, has no business coming from the lips of the righteous. There is no misunderstanding the apostle; fornicators, the immoral, the covetous and idolaters will not inherit heaven. Christ can save you from these sins, but, if you continue to commit them, you will not inherit heaven. Do not rationalize and remain in these sins; repent and renounce them all.
