It looks like you have a wrong understanding of grace believers and confessing sins...here is an article that discusses all about that subject as obviously you have been mis-informed.
There are a few articles in this link. I use this website because it tackles the obscure scriptures and the mis-information about grace...sometimes the comments at the bottom of the articles are great too as people can ask questions..

I'd rather not re-hash all this stuff until you have at least looked at it as it has been already been talked about in a number of threads here for months....thanks...
Back in the day, doctors ordered tests so if I switched doctors, they didn't honor the tests that I had unless they did it. Why would that be? It was be cause they were trying to be as accurate as possible.
I am not concerned if you have to rehash what you have posted here because (1) there is low church attendance here or people are getting milk at some of their churches and (2) it requires someone to work and desire to look everything up and fact check it for assumptions, logical errors, hermeneutics errors, definition errors, etc. (3) There is a lack of credentialed people here defending the faith who have seen this error thousands of times. There is nothing new under the sun and this teaching wasn't practiced in the book of Acts because Paul rebuked Peter to his face and James came down with Jewish brethren to put us back under the law and everyone has heresies.
More times than not, it is the ones with novel doctrines that have the followers who get on t.v. but fewer the righteous ones.
