There is a Major flaw in your argument, When we place yourself. Myself. and this person who is an adulterer and bigomist up against the Law, We see that we all three fall short of the glory of God and non of us are worthy.
So if your going to look at yourself as compared to this person to see who is saved or who is not saved, or who is more worthy to be saved, or whatever, Your not looking at the correct standard. (I know. legalists do not like to hear this, the phairsee did not either, thats why they crucified Christ, You want to crucify me? Feel fre. I will be in heaven sooner)
Now. what would I do with them? I would do what the bible tells me to do with them, And trust God that God can change them, in whatever it would take to change them. Knowing I cant change anyone, I can just suggest. It is not my place to judge,
So can we get back to the issue of the gospel. and not these wild goose chase ad hominem arguments which does nothing to help us focus on the real issue.
