During this article, I would like to address a specific implication of American Christianity's mode of legalism as it applies to speech. Hopefully this article will be both thought provoking and edifying to those who read it.
Quite frankly, the issue at hand is that we have allowed legalism to rule so much of our lives, that we have actually created an exact (or nearly so) list of "bad words," as though one's heart is judged based on their word choice, rather than on their faith or obedience to God.
You may not believe me, but try using any one of society's list of "cuss words" in the context of the church body, and just see how well it sits with the people. You don't really have to try this to know that it's true In fact, you probably shouldn't for the sake of avoiding being a stumbling block to them. However, let's say that you did try this. You may find that, even if you use one of these words in the context of trying to encourage someone (for example: "You're the nicest f@!#ing person that I know, and I wanted to let you know how much I care about you."), they will ignore everything else that you say in the conversation because of one simple word that we have deemed as horrible. Furthermore, they will not even consider where your heart is in saying this.
What is even worse is that one can have a horribly harsh attitude when speaking to someone, but they will be pardoned as pure in speech because they have not employed any of the technically "bad words." For example, "Why haven't you finished this one simple task that I asked you!? Was it really that hard!? I've never met someone so lazy in all my life!" They never technically "swore," but I really don't believe that "swear words" are the issue at hand here. Let's see what God's Word has to say about our language.
In Paul's letter to the Ephesians, specifically in Chapter 4, versus 29-32, he wrote: "Let no corrupt word proceed out of your mouth, but what is good for necessary edification, that it may impart grace to the hearers. And do not grieve the Holy Spirit of God, by whom you were sealed for the day of redemption. Let all bitterness, wrath, anger, clamor, and evil speaking be put away from you, with all malice. And Be kind to one another, tenderhearted, forgiving one another, even as God in Christ forgave you."
So, as you can see, God instructs us to use our speech in a way that not only avoids bitterness, wrath, etc., but instructs us to specifically use our speech for necessary edification. Obviously it is not a matter of which technical words that we are using. One can not defile language with words, but with the heart behind them. As The Gospel Accord to John, chapter 4, verse 24 states: "God is Spirit, and those who worship Him must worship in spirit and truth." When Jesus said this, he was speaking to a woman who was obsessed with the idea of her status with God being based on where she worshiped, what heritage she had, her social status, etc. Jesus told her this to get her to realize that it is the state of one's spirit and heart that define one's relationship with God, rather than our physical actions. Of course I realize that most physical actions are a reflection of the heart - don't get me wrong - but in and of themselves, words and actions can not be sinful.
In conclusion, the reason I say all of this is not to justify being able to say swear words. In fact, I would actually recommend avoiding them when possible, since, due to society's misunderstandings, these words could easily be used against Christ's testimony. However, I also don't think that we should by any means condemn people for using these words. Moreover, I am upset over this issue, because we have strayed away from the purpose of our speech. We should be focused on using our language to, as stated earlier in Ephesians, to edify each other, that it may impart grace to the hearers. Our goal in life is to be proactive for the kingdom, not just deactive against the enemy's. If we spend all of our time condemning people for wrongs that we're not even able (or allowed) to judge them for, we will never take the time to observe how our actions can be used for God's glory, and we will never overlook the small problems in life to see the larger ones at hand.
