You seem to be placing an enormous emphasis on your own obedience.If there is anyone having justification by faith-alone apart from works, that is not justified by faith-alone while doing an evil work, then say so.
You've be the first.
But, if faith-alone justifies while committing sin against Christ, then ceasing sinning against Christ is not necessary to be justified by faith-alone.
I know where you get this wacky hogwash, that faith-alone justification includes cessation from sinning. But you would do well to ACTUALLY say so, instead of throwing irrelevant criticism at what you erroneously ASSUME other faith-alone Christians believe.
Go ahead and declare that faith-alone does not justify any man, that is doing any evil deed.
1Jo 3:8
He that is committing sin is of the devil; for the devil is sinning from the beginning.
Here is a simple passage by Paul and hopefully you can, zero in, on the reason for your salvation.
Colossians 1:22-23
In the body of His flesh through death, to present you holy, and blameless, and above reproach in His sight—
if indeed you continue in the faith, grounded and steadfast, and are not moved away from the hope of the gospel
which you heard, which was preached to every creature under heaven, of which I, Paul, became a minister.
Jesus justifies us, Jesus sanctifies us, Jesus makes us holy, Jesus declares us blameless!
IN HIS SIGHT
All this belongs to Jesus and we cannot generate any of this ourselves.
That is why we boast in Jesus alone for our salvation.
