This, then, is the foundation of sanctification in Reformed theology. It is rooted, not in humanity and their achievement of holiness or sanctification, but in what God has done in Christ, and for us in union with him. Rather than view Christians first and foremost in the microcosmic context of their own progress, the Reformed doctrine first of all sets them in the macrocosm of God's activity in redemptive history. It is seeing oneself in this context that enables the individual Christian to grow in true holiness.

Sinclair B. FergusonChristianity is Christ because there isn't anything else. There is no atonement that somehow can be detached from who the Lord Jesus is. There is no grace that can be attached to you transferred from Him. All there is, is Christ and your soul.
Sinclair B. FergusonThere are actually only ever two pastoral problems you will ever encounter. The first is this: persuading those who are under the dominion of sin that they are under the dominion of sin. That's the task of evangelism. And [second], persuading those who are no longer under the dominion of sin that they are no longer under the dominion of sin because they're Christ's.
