Jesus says that His brothers and sisters should not even be using such seemingly mild exclamations as "Good heavens!" They are unnecessary, and more than that, Satan and his anti-God attitudes influence them.
Certainly, church members are not using four-letter words or blaspheming or profaning God's name. In part, the third commandment—prohibiting taking God's name in vain—deals with such matters. Rather, the words that some complain about are of another type: mild or watered-down versions of God's names or crude words for certain body parts or bodily functions. Though this sensitive theme may embarrass or offend, it needs to be covered.
For those who might be new to this subject, it is necessary to give warning about "substitute" swearwords such as "gosh," "golly," "jeez," "shoot," "shucks," "heck," "darn," and others. Such words are called euphemisms, literally "good speech." It does not take much thought to figure out what words these exclamations are substitutes for. We do not need them! The English language contains thousands of benign yet descriptive words and expressions that convey the same feeling or reaction.
Yet for those whose speech habits are deeply ingrained, it can be hard. Many of us have used bad language freely and frequently before conversion. Many of us are surrounded by foul language at work every day. A friend told me that, upon starting a job "in the world" after spending four years at Ambassador College, he was plagued by swearwords constantly coming to the tip of his tongue for the least little problem!
I do not wish to appear self-righteous in discussing this sensitive subject. I am not pointing a finger at others. Like many church members, I work in an office where I cannot even enjoy a cup of coffee with my coworkers because the air so frequently turns blue with bad language and filthy subject matter. Some of the women are as bad as the men—in some cases, worse! It can rub off on us and, like the proverbial frog in hot water, we can gradually come to accept gutter-language as the norm. We can become calloused to it, and we can allow it to creep into our everyday conversation.
Swear Not at All!
