It's my belief, and I don't know for sure, but we are ultimately sanctified when we are in God's kingdom, and given such knowledge and understanding that we will no longer want to sin.
Before answering this let me just say that I appreciate the "real person" way that you present yourself. I got a kick out of the way you answered FaithWillDo "Dude I'm not reading all that".. LOL
I'm sure I tend towards answering too matter-of-factly, but I'm finding value in expressing my humanity once in a while. Don't let go of yours in the BDF. It's an asset.
OK.. in answering the quoted portion of your post, I'm just answering from an experience with God, so you can do with it as you see fit. And (at time of typing this) I have no intention to try to back it with many scriptures other than the ones that came to mind as this happened. And I'll only give the details that are pertinent to your musing.
I was lying on my bed when I felt the power of God coming upon me in a way that I knew was so he could teach me something. Basically it was as if his presence was coming into the room.... awesome/pleasant/powerful/inspiring adoration.
I'm a sincerely analytical person (and a bit worried about being worthy to stand before God,) so I was noting what I was experiencing AND checking how I was feeling about it, etc. Was I afraid? No. Did I expect it to last forever? No. Did I feel like I was supposed to do anything? No. Did still I still feel like myself? Yes. (And the important one...) Did I still have "my" sins with me? (not those removed through salvation, but the ones we picked back up because we LIKED them)
...And here's were it connects with your supposition about losing the sinful nature/inclinations...
My answer to the question of "Did I still desire to sin" would be... "Sort of".
As the presence of God grew stronger and stronger I noticed the desires to do specific sins were disappearing. So I focused on that one sin... that "pet" sin... the one the bible refers to as "the sin which doth so easily beset us" (Heb. 12:1) I assume it's different for each of us, but I knew mine. So I checked to see if it was still present... if I still had the desire towards it...
And at first, Yes. It held on longer than any others... but eventually the desire for it, too disappeared. I can only liken it to a fly clinging desparately to a windshield as a car accelerates. It may hang on for a little while, but if we're heading towards interstate speeds, it's only a matter of time until FLIT.. and it's gone. I even wondered
where that desire went because it was GONE.
All had been replaced with the sincere desire to do ONLY what was
right and pleasing to God. And I remembered the scripture that says "
In his presence is fullness of joy". Then it was over. The presence and power lifted, and I was left clawing at the sky trying to keep it.. LOL
So I have little doubt that every desire to sin will be utter replaced with sincere desire to do only that which is good and pleasant in his sight (at least in those who are ultimately invited into his presence).
I hope that was at least interesting, and hopefully even beneficial.
Love in Jesus,
