Fair enough.
. We can discuss it.
I agree completely. We have been set free, past tense. Then, present tense, we are slaves to God. We have to be one or the other, no middle ground.
So, as the passages says, "the fruit you get" from this slavery to God, "leads to sanctification" - which is to say, the fruit(works) we see is what is purifying us - setting us apart.
The end of this purification process, as it is with gold or any other precious metal, is complete holiness - set apart. When Gold is purified, it is set apart from the dirt in it.
So, when this process is done, "its end is eternal life".
Consider this. Where does sin come from? Is it just my flesh, or is sin when I desire something from my heart?
What is the sanctification process for? Is it to conform my flesh/body, that will die, or is it to conform and purify my heart?
Now ask yourself this. What is eternal life? No, not just 'life' that's eternal. What is it?
It is Christ. He is the eternal life. Do you posses Him, or does He posses you?
Now, can God physically inhabit you when there is sin? No, but He can through faith. So until you are completely pure, God cannot fully abide in you - except through faith.
Once you put off this flesh, then you will put off the man of sin, you will be transformed and no longer will there be any sin.
You will then be in perfect condition for God to live in you, and the result of that is eternal life.
