But the Lord does in His Word which you should be paying attention do concerning sin and what sin brings upon a person
People don't live in sin because they think all their sins are forgiven
Christians all over the place are doing exactly that. If Christianity became illegal most Christians could not be convicted due to a lack of evidence that they are Christians.
People live in sin because their hearts are darkened and they make excuses and rationalizations for the satisfaction of their desires.
And because the false grace teachers tell them that all future sins have already been forgiven claiming they are still saved even if they live in sin, and now we have all these Christians living in sin. It's thew end times falling the Lord warned about.
Why would they care?
Most don't which is why it's hard to tell the difference between most Christians and people out in the world that never knew God

#2 - Specifically, what part of Romans 6 are you speaking of?
