Exactly...it's talking about habitual, known, deliberate sin, not the spur of the moment, moment of weakness type, for which there is forgiveness proffered.
Unfortunately, today, many put "sin" under one umbrella, see themselves making mistakes due to character flaws which have not yet been healed by the Holy Spirit, and then throw up their hands and say, "Well, nobody can keep the law, so let's invent OSAS so that we can still go to heaven."
