Then comes up another question ... WHO and WHAT chooses/defines/decides what's an "incorrigibly wicked" people ...
I may judge someone "incorrigible wicked" yet another person may find him/her a "loving" person.
When you judge people under the LAW (like Watchtower and JWs) we are all "incorrigible wicked" as we will never be able to obtain perfection to be acceptable in front of God ...when you are under GRACE ... you are "lovable" ... even if your transgressions are red as blood, God through GRACE sees all White as snow ...
Law demands perfect obedience
GRACE supplies perfect obedience, it is given to us through my LORD and SAVIOUR JESUS
My niece, who was sexually abused by 3 different JWs is considered "incorrigibly wicked" by Watchtower's standards as she doesn't want to go back to being a JW (she knows the truth about the truth now) - they'd rather see her commiting suicide than show mercy to her and let her choose JESUS as her Lord and Saviour, her MEDIATOR not any bunch on old men in New York some now we know haven been homosexuals.
"I found his line of reasoning refreshing" - Sorry ... in the Christian context, the bible is clear as to whom will be saved ... and it has nothing to do with "works/law" - it has to do with who you believe in ...
