Define "unrepentant"...? Since none of us with a full knowledge of sin, cannot stop sometimes committing sin that we know is a sin sometimes, or feel might be a sin in some situations and cases (but may not be) (in certain moral situations where you see or feel that true justice might be making an exception to the rule(s) in some cases)... Anyway,
I smoke cigarettes, it's a known sin, I know it is a sin, yet I do it, cause I'm addicted, and also partially due to some mental health issues, but it is a sin, and a known sin, now does that keep from being in a saved state all the while I am doing it...? I don't think that is the case... I've grown up from thinking that... I am "repentant" about it, but I have not repented yet...
And what about ignorant letter of the law people, who reject the truth and do or will not (as in they choose not to) see all their own sin...
The facts are no one can be sinless, except Jesus... And I definitely do not see anybody on here or anywhere (with my full knowledge of sin) that is sin free completely, that's the logic problem involved here, and with telling someone that they must be perfect of sin free and never sin again or they'll lose their salvation or never had it in the first place...
If you are telling people that and teaching that then you are very, very wrong and do not understand God, Christ, or the gospel at all...
God Bless!
