If you are asking about this, your conscience is probably telling you something and you obviously are not sure (ie. you doubt) about it.
Apply the rule Paul gave in his letters - do not do what you are not certain about, its a sin.
"But whoever has doubts is condemned if they eat, because their eating is not from faith; and everything that does not come from faith is sin."
R 14:23
Well I'm not asking because I have doubts. I'm not sure if you got what I was asking but I wanted to see if anyone notices how 'normal' it is that Christians cuss (more so the profane words). I think its wrong for a Christian to use profane words. The FCC does too! So if its wrong in the world, what are WE doing using it so casually? I think it involves a watering down/lukewarm effect and ultimately involves falling away if we don't turn back from it.
