Read the scripture right before that one:
8 If we say that we have no sin, we deceive ourselves, and the truth is not in us.
Did you read how he says there is NO TRUTH in us?
That is about people who claim to be saved but who never repented of their sins because they said they did not have sins.
That scripture proves we have to repent of sins to be saved.
Could you please define "repent" in the terms you believe it brings salvation? If your concerned about us heathens not making it in the pearly gates, it would be nice to know your perspective.
