Brother Bob said:So, if I get scripture that says "sin" you will accept it as one sin?
It depends on the context and the tense. In some cases it's a sin. In other cases, it means to sin continually. I can't give you examples of which is which without the Greek in front of me.
In practical terms, it makes no difference. We should flee sin, period. But the difference is important if you want to really understand what the author is saying in one place or another.
