Sounds like something a Pharisee would say. Doesn't sound like something Jesus would say though.
Jesus told Paul to say it for him...
2Co_13:5 Examine yourselves, whether ye be in the faith; prove your own selves. Know ye not your own selves, how that Jesus Christ is in you, except ye be reprobates?
I'm sorry if I sound disrespectful but why are you trying to discuss things Christian when you don't even know what the bible says???
You do sound disrespectful.
.. . but why are you trying to discuss things Christian when you don't even know what the bible says???
See, this is you sounding disrespectful again. For the record, I actually nailed it. I said it sounded like something a Pharisee would say. Turns out that a Pharisee did say it.
And as I pointed out before, Paul wasn't saying that if they couldn't comprehend what he said, then they should examine themselves. The original question you were asked is whether you sin or not. And instead of being forthcoming, you dodged it, posted some scripture that was totally unrelated to the question at hand, and then admonished another for not comprehending what turns out was an error on your part. And that is not at all what Paul did to the church at Corinth.
