Hebrews 2:10-13 (ESV)
For it was fitting that he, for whom and by whom all things exist, in bringing many sons to glory, should make the founder of their salvation perfect through suffering.  For he who sanctifies and those who are sanctified all have one origin. That is why he is not ashamed to call them brothers,  saying,
"I will tell of your name to my brothers;
in the midst of the congregation I will sing your praise."
 And again,
"I will put my trust in him."
"Behold, I and the children God has given me."
For he who sanctifies and those who are sanctified have one origin. The Holy Spirit sanctifies by the blood of Christ. We are sanctified. I return to this topic so often because it is perhaps the most pernicious topic of the day. I hate it when people talk of sanctification as a process. I know we grow in faith, love, and knowledge by the work of the Holy Spirit in us. There is much to learn even after one becomes a Christian. But let’s not talk about this in legalistic terms like our “evangelical” neighbors that have no idea what the evangel is. When the Book of Concord talks about the third use of the law, it is not talking about American evangelical sermon exhortations. It is talking about function of the law operating in us through the work of the Holy Spirit. You don’t preach “third use”. You preach law. Then you preach Gospel. We don’t train our members to be hypocrites, and Pharisees. We don’t measure how sanctified or unsanctified we are based on the law. Sanctification is the result of the gospel. You are or you are not sanctified. If you are not sanctified you are not saved. How can God save that which is not Holy? How can he save it without making it holy? How can he pour his blood over us, and atone for our sins with it, without making us Holy? Sanctified=made Holy. When we do as so many are proposing, and blend the “3rd use of the law” (as if it was a blond we picked up at the bar for the third time, being as you used her twice already.), and throw it in the realm of sanctification as something we need to achieve because we “cooperate in sanctification,” we are back in Rome. The whole third use controversy is nothing but an attempt of 3rd rate theologians to cloak Wesleyan Progressive Sanctification in Lutheran terminology. Stop. If you want to be an evangelical go rent a store front and do it. I can’t stop you. But please stop calling yourself Lutheran.
