Every Christian knows why cuss and curse words are both forbidden...even if to the 'course, brutish, and oafish' it is hard to explain why they are wrong...but I will try to be as clear as possible and show why in many different ways.
First, when you cuss you are not calling on the Lord when you are in distress, but instead are actually cursing the moment and God...
Second, the Bible says people will be judged for every word they speak...and words are meant to give life not death, which all cuss words do...
Third, as said before, instead of explaining how you are feeling or being more expressive about the poignant feeling about whatever, cussing is VERY rash...
Forth, can you imagine Jesus cussing? Obviously not...
Fifth, cuss words are part of 'the language of darkness'....meaning it is something that is used to obscure and deform speech, even breaking down grammar in those who are perishing...thats why they use 'cuss words' almost every other word and lose the connection of the sentences they form to meaningless emphasis...
Sixth, the f word has to do with corse sex and not love...and if it was not attached to this meaning it would not be a curse word, but thats where it draws its emphasis or 'death' from if you will...the b word also draws its meaning from a female dog, and as so, has to do with corse sex and thats where it draws its emphasis from, even if it is used in other ways, it drags this meaning along as well...the d word has to do with condemning something to hell and we are not to curse anyone, and also draws its life from the death of its original meaning...the a word has to do with a course word for a buttocks, hence why it is evil, corse sexual under tones here as well...the s word is a course word for poop...which is also used to condemn things and also to throw 'filth' into vernacular in order to make it vulgar...which word am I missing?
In short, cuss words are not holy nor do they make anyone holy who uses then (remember we are commanded to be holy even as the Lord Jesus was holy)...but rather they set that person apart as profane...because words are the most important thing we have, it is words that are suppose to give us life, and instead the person who cusses has become rash and thus becomes more and more callous to why they are wrong until they declare...Why are cuss words wrong? If you remembered back when you were young and the sick pleasure you found from cussing, then you would remember loosing the innocence in your speech, and also loosing life...but that day is often tooooo far back for those who see nothing wrong about cussing, thus it is impossible to proove why it is wrong because you can no longer see the evil of it...
I hope this helps...but often those who cuss do not see innocence anymore (or atleast innocence in themselves or in their speech) whatsoever.
A true Christian knows cussing profanes the name of God that they have become in order to call themselves Christ-ian...
Much more to say
May the Lord purify those who seek holiness and innocence in truth and righteousness
