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. FergusonFailure to deal with the presence of sin can often be traced back to spiritual amnesia โ forgetting our new, true, real identity. As a believer, I am someone who has been delivered from the dominion of sin and who therefore is free and motivated to fight against the remnants of sin in my heart. You must know, rest in, think through, and act upon your new identity โ you are in Christ
Sinclair B. FergusonRemember that you are not saved by increased levels of holiness, however desirable it is that you should reach them. ...It is Christ who saves us-through faith. Your faith is a poor and crumbling thing, as is your spiritual service. Jesus Christ alone is qualified and able to save you because of what He has done.
Sinclair B. FergusonThere is a difference between going to a service "for the worship" and going to a service "to worship the Lord." The distinction appears to be a minor one, but it may imply the difference between the worship of God and the worship of music!
Sinclair B. FergusonWhen the New Testament speaks about the fullness of grace which we find in Christ, it does not mean only forgiveness, pardon and justification. Christ has done much more for us. He died for us, but he also lived for us. Now he has sent his own Spirit to us so that we might draw on his strength. He grew in grace, and when we draw on his power we shall likewise grow in grace.
