You ask a lot of questions but make no statements
There is a difference between what we mean by 'sinful nature' and what you mean by 'sinful nature'. I will proceed with this one when you tell me whether or not you believe in Original Sin.
I guess my question is do you even know what a sin is? well listen up
1Jn:3:4: Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law.
If you feel Jesus transgressed the Law then you are just wrong. You do believe the bible dont you?
So tell me since you brought it up. What is the Original sin?
