It appears that you'd read something into my posts that I did not write.
To remain a believer is NOT a work.
Yes, you are calling belief a work by saying you must maintain a certain “level” of belief (your undefined and vague standard which salvation by works always is which is BTW, the same as Muslims - they never know for sure if they’re going to heaven) to remain saved. That is YOU turning “belief” into a work. Once you are saved you remain saved because it is by grace NOT works. I’ve been over this more than once with you.
Good bye and good luck.
