what happened to progressive sanctification?

@darkveggie - The focus on sanctification, even progressive, seems misplaced, considering when Paul gave thanks for people being Christian in the openings of his epistles, he never seemed to say anything like, "I thank God that you are being (progressively) sanctified," but more "I thank God that your faith in God is increasing and that your love for others increasing, too."  See especially Ephesians 1:15–16, Colossians 1:3–4, I Thessalonians 1:2–3, II Thessalonians 1:3, and Philemon 4–5, and in the rest of the epistles in which Paul thanks God (Romans 1:8, I Corinthians 1, Philippians 1, II Timothy 1:3–5), he doesn't seem to care about obedience or purity or holiness or anything else that we seem to associate with sanctification, and that these seem to be convenient side effects of the love and faith that he wants us to really go after.

@Aidje - Everything before the postscript is addressed to all Christians.

I guess I only have this to offer:  1 Corinthians 8:9.

Be the light, and make sure the world isn't perceiving darkness.

Rom. 13: "And do this, knowing the time, that now it is high time to awake
out of sleep; for now our salvation is nearer than when we first
believed. The night is far spent, the day is at hand. Therefore let us
cast off the works of darkness, and let us put on the armor of light.
Let us walk properly, as in the day, not in revelry and drunkenness,
not in lewdness and lust, not in strife and envy. But put on the Lord
Jesus Christ, and make no provision for the flesh, to fulfill its
lusts."

2 Tim. 6: "But you, O man of God, flee these things and
pursue righteousness, godliness, faith, love, patience, gentleness. ...
that you keep this commandment without spot, blameless until our Lord
Jesus Christ’s appearing,"

James 1:27, "Pure and undefiled religion before God and the Father is this: to visit orphans and widows in their trouble, and to keep oneself unspotted from the world."

Col. 3: "1 If then you were raised with Christ, seek those things which are
above, where Christ is, sitting at the right hand of God. 2 Set your
mind on things above, not on things on the earth. ... 5 Therefore put
to death your members which are on the earth: fornication, uncleanness,
passion, evil desire, and covetousness, which is idolatry. 6 Because of
these things the wrath of God is coming upon the sons of disobedience,
7 in which you yourselves once walked when you lived in them. 8 But now
you yourselves are to put off all these: anger, wrath, malice,
blasphemy, filthy language out of your mouth. 9 Do not lie to one
another, since you have put off the old man with his deeds, 10 and have
put on the new man who is renewed in knowledge according to the image
of Him who created him, ... 12 Therefore, as the elect of God, holy and
beloved, put on tender mercies, kindness, humility, meekness,
longsuffering; 13 bearing with one another, and forgiving one another,
if anyone has a complaint against another; even as Christ forgave you,
so you also must do. 14 But above all these things put on love, which is the bond of perfection."

Also, Romans 6.  The entire thing.
