Right - drinking is not a sin! Agreed! Getting drunk is! Ephesians 5:18 (As I said elsewhere, Lightskin, said "drinking".)
Cussing - It depends what is meant?
The dictionary says cussing is short for cursing - and cursing someone surely is not very Godly!
First thing google says is this: What are cuss words? Profanities can also be called curse ("cuss") words, dirty words, bad words, foul language, obscenity, obscene language, or expletives. It can be called swearing, although this also has a normal meaning of making a "solemn promise". A profanity usually refers to religion, sex, or bodily functions. Lightskin told me he mean 4,8,12 letter words.?? If those words are meant to edify and do good - wonderful! If not, then I don't want him on my property around my children!
Having sex with his girlfriend - should his church deal with it? Absolutely, but if he brings it up on CC I am going to address it as sin!
Do I have struggles with sin? Absolutely, I have struggles with sin, and I have no problem with someone admitting struggle with sin, but I do have a problem with someone who admits sin but does nothing to overcome it. Which is Lightfoot? I don't know for sure. If he wants to overcome it and has a heart for God (as he says), he will want to live in victory over sin.
