If you get a chance to read what he has written and all of the responses please do so. I am providing a citation below that may help one understand how there truly is unity and a direct connection between what Lutherans call "justification" and "sanctification." The following words come from St. Cyril as he writes on the Gospel reading for Cantate (Easter 5) (cf. Jn. 16:5ff):
All that the Lord had to do on earth was now done; but it was necessary that we should become sharers and partakers of the divine nature of the Word, or rather, that giving up of our old life we should be changed to another, and be reformed in newness of life in a manner pleasing to God. But it was not possible to to do this except through the possession and communion of the Holy Spirit. (St. Cyril, cited in Toal, Vol. II, p. 386)
In other words, we do not simply say, "God has done His part" (ie, "Justification") "now we must do our part" in response (ie, what is called "Sanctification"). Rather, as we know in Baptism, the same Lord who justifies is the one who sanctifies. Cyril's quote is an example of the understanding, as we see in John 16, that sanctification is more than a mere response of doing good - it is the actual work of the Holy Spirit who comes to us in Baptism, in Preaching, in Absolution, in Holy Supper. So while the Lord comes to us extra nos, He does not simply keep His distance but actually lives in us (ie, Gal. 2:20). Therefore, the Scripture clarifies that the justified person does cooperate with the Holy Spirit because the Holy Spirit, that is, Christ, is leading him/her to do so. Therefore, what the sinner is led to do are actually "good" works because they are works which God is doing in and through us.
In brief, justification and sanctification are good ways to understand different works of the same Lord. However, the Lord is not divided in His work outside of us and inside of us (ie, "communion of the Holy Spirit") and this is where focusing on the distinctions may cause confusion in the unity that actually exists between "justification" and "sanctification." Our salvation is a united work of God in Christ. The Spirit does not stop justifying and then say, now it is time to sanctify.
