As a Sunday school teacher I can assure you there are people who I wish I could tell them they are bad Christians.
I don't consider myself perfect I know I have my faults. But some claim to be pure due to being Christian when truly they are pure shit.
That's kinda the point. The goal is to become a good/Godly person the problem is that better you get the more you realize how bad you are. Paul considered himself the chief of sinners but I don't think I'd ever like to be compared to him.
The whole point of Christianity is to realize that you are NOT a good person. That you cannot be a good person on your own. Nobody can. That's why you need Christ.
