So... Christian Twitter (specifically thinking friends/followers here), what would you say to someone who is trying to tell you, using the verses listed below as “proof”, certain sins (beyond just unbelief) will disinherit a person from saving grace?

We’ve already discussed how repeated sin can lead to active rebellion/apostasy, but she’s CERTAIN the verses about that mean God withholds forgiveness. Just curious if there’s a simpler/clearer way to say this, as for some reason she doesn’t seem to understand my explanations
