Does the lamp have the ability to light itself?
Does the clay determine what shape the potter will make it?
Did the tabernacle and the priestly garments declare themselves sanctified?
There is never a time in Scriptures were the word sanctify is used as some human ability to attain to any "set apart state" nor the ability of humankind to set them self apart.
Too often the "progressive sanctification" advocates taking verses of scriptures that discuss the determination of the believer to live a life of holiness and growing in the knowledge and grace of God as sanctification.
It is not.
It does not fit the definition nor the application of how the word is used in Scriptures.
Not accepting the view of "progressive sanctification" in NO WAY diminishes the need of the believer to grow in Christ and work diligently to separate from the worldly.
The verse you posted serves very well to emphasis the believer is responsible to separate from the worldly.
But, that isn't sanctification.
Remember, when the word is used, it is always in the context of what is accomplished by performance upon (be it believer, priest, tabernacle...) and not some change or movement generated from within that (believer, priest, tabernacle...) "progressively sanctifies."
OK. Does it just boil down to the terminology one is using? I'm not up on what goes on in the popular evangelical arena, is a conflict concerning 'progressive sanctification' going on with you all? I've always thought of sanctification as having 'two sides'. I kinda sorta think we're actually not far apart on what we believe, just not using the same terms.
