So which is not a possibility?
In your imagination anything is possible, who knows the context other than you.
You made a limited hypothetical where I point to God starting in someone being the factor which would separate what is and is not possible.
Then I point to examples of what happens in God's children who sin opposed to unbelievers to futher what can be evidence to oneself.
You admit all men sin.
Then say sin comes from the heart as if that would stand against my point that after God works in us, though every man sins, which sort of man is sinning FEELS differently about sin.
This is so fruitless, your stories and boxes and arguments fall short of helpful to anyone who knows God or seeks truth.
You may desire to "stir thought" but I have mainly seen confusion and miss application of what others are saying from you.
You haven't even owned up to the specifically saying "its not a yes or no" then imputing yes or no to answers.... also asking "is that a yes or no" to responses despite others saying "it's not yes or no"
all while referring to the original question...
