Sanctification upon Justification...

• It seems that part of the confusion is the notion that when we’re talking about our sanctification we shouldn’t be referring to our justification, otherwise… well, otherwise what? Is it not fair to say that our justification, in some sense, is the ground upon which we live and walk the sanctified life? If I am sanctified daily through the work of the Holy Spirit can I any more move beyond the justification secured for me by Christ Jesus on the cross then when I go to the store I can leave the ground of the sidewalk upon which I walk? Not a perfect analogy certainly, but… Every grace of sanctification in the believer's life is logically secured upon the justification wrought for him in the finished work of Christ Jesus.
• The old hymn reads, "On Christ the solid rock I stand, all other ground is sinking sand…" I don’t think this is speaking of conversion, but of living the Christian life.
• There is no work of ours that is sanctified except that the blood of Jesus was shed for us (Heb. 9 and 10). His finished work then is the basis by which our persons as well as our works with their remaining imperfections are cleansed, allowing them (and us) to be acceptable to God by grace through faith in Christ alone.

• I’ve always found these words of Paul in Romans 7:18 to be intriguing (assuming this is the converted Paul, which I do):
• "For I know that nothing good dwells in me, that is, in my flesh. For I have the desire to do what is right, but not the ability to carry it out."
• I don’t think Paul is saying that he doesn’t offer his members unto righteousness or that he doesn’t make efforts to resist sin and obey God's law. Could it be it's just that he (we) never graduated from needing the sufficiency of Christ’s atonement in order that his every thought, word, and deed be cleansed and made acceptable to God? For none of Paul's good works could attain to the perfection of the Law anymore than ours can, that perfection of the Father in heaven to which he and we are called. He lacked the inherent holiness or "ability to carry it out." So, in our walk of obedience to God as we daily offer ourselves up as servants for righteousness (Rom. 6: 13), and in order that our consciences may be comforted, we must always keep our eyes not only on the law of Christ to guide our obedience but on the good news that "There is therefore now no condemnation for those who are in Christ Jesus." (Romans 8:1 ESV)

• WCF 16: 5. We can not, by our best works, merit pardon of sin, or eternal life, at the hand of God, because of the great disproportion that is between them and the glory to come, and the infinite distance that is between us and God, whom by them we can neither profit, nor satisfy for the debt of our former sins; but when we have done all we can, we have done but our duty, and are unprofitable servants: and because, as they are good, they proceed from his Spirit; and as they are wrought by us, they are defiled and mixed with so much weakness and imperfection that they can not endure the severity of God’s judgment.

• 6. Yet notwithstanding, the persons of believers being accepted through Christ, their good works also are accepted in him, not as though they were in this life wholly unblamable and unreprovable in God’s sight; but that he, looking upon them in his Son, is pleased to accept and reward that which is sincere, although accompanied with many weaknesses and imperfections.

• WCF 9:4 underscores my point above -

• 4. When God converts a sinner and translates him into the state of grace, he freeth him from his natural bondage under sin, and, by his grace alone, enables him freely to will and to do that which is spiritually good; yet so as that, by reason of his remaining corruption, he doth not perfectly, nor only, will that which is good, but doth also will that which is evil.

• Even our good works which we will to do, i.e. our obedience, are imperfect and still touched by the corruption of sin. Yet as new creatures in Christ we can and do will to do good. We can obey. But far from perfectly and not without sin. The ground of acceptance of our good works before God our Father is Jesus Christ our Mediator – His cleansing blood shed for us and perfect obedience imputed to us - not any inherent goodness found in our obedience. (WCF 16:6)
• Therefore we confess that as believers we should obey. We can choose to obey. But in this life we never can offer an obedience to God that is pure or acceptable in and of itself, i.e. never free from the inherent corruption of our fallen nature. Thus the gospel (justified freely in Christ Jesus by grace through faith alone) is always relevant, even central, to our sanctification.
