You don't believe the bible at all if you believe that.
2 Peter 2:9 The Lord knoweth how to deliver the godly out of temptations, and to reserve the unjust unto the day of judgment to be punished:
2 Peter 2:9 The Lord knoweth how to deliver the godly out of temptations, and to reserve the unjust unto the day of judgment to be punished:
If one is preaching something false, in this case works salvation and the lie of having sinless perfection, that person is under those terms. You can't teach a false gospel, then meet the Lord on terms of the true gospel, have a false confession that saves. As you mention, their confession is actually not having faith in the gospel to save, which demonstrates a misunderstanding of faith that cannot trust God and His promises, does not trust grace and the finished work of the Lord Jesus.
You put the whole picture together, and it's senseless: it doesn't fit together as a credible faith anybody could have. These people either are insane, or deceivers who don't really care about salvation, are here for trolling or the devil, though one in the same, when their behavior involves perversion of the things of God. They are simply trying to refute the true faith and raise doubt, or are merely trolling to offend, if I have to say it a thousand times.
They can't give a coherent answer for what they believe, of these important issues you raise. What those carrying a false gospel are demonstrating, for whatever their reasons for these perversions, is a need to be saved.
Galatians 2:4-5 And that because of false brethren unawares brought in, who came in privily to spy out our liberty which we have in Christ Jesus, that they might bring us into bondage: to whom we gave place by subjection, no, not for an hour; that the truth of the gospel might continue with you.
