Q & A 75
Q What is sanctification?
A Sanctification is a work of God’s grace, whereby they whom God has, before the foundation of the world, chosen to be holy, are in time, through the powerful operation of his Spirit *1 applying the death and resurrection of Christ unto them *2, renewed in their whole man after the image of God *3; having the seeds of repentance unto life, and all other saving graces, put into their hearts *4, and those graces so stirred up, increased, and strengthened *5, as that they more and more die unto sin, and rise unto newness of life *6.
Q & A 76
Q What is repentance unto life?
A Repentance unto life is a saving grace *7, wrought in the heart of a sinner by the Spirit *8 and Word of God *9, whereby, out of the sight and sense, not only of the danger *10, but also of the filthiness and odiousness of his sins *11, and upon the apprehension of God’s mercy in Christ to such as are penitent *12, he so grieves for *13 and hates his sins *14, as that he turns from them all to God *15, purposing and endeavouring constantly to walk with him in all the ways of new obedience *16.
Q & A 77
Q Wherein do justification and sanctification differ?
A Although sanctification be inseparably joined with justification *17, yet they differ, in that God in justification imputes the righteousness of Christ *18; in sanctification of his Spirit infuses grace, and enables to the exercise thereof *19; in the former, sin is pardoned *20; in the other, it is subdued *21: the one does equally free all believers from the revenging wrath of God, and that perfectly in this life, that they never fall into condemnation *22 the other is neither equal in all *23, nor in this life perfect in any *24, but growing up to perfection *25.
Q & A 78
Q Whence arises the imperfection of sanctification in believers?
A The imperfection of sanctification in believers arises from the remnants of sin abiding in every part of them, and the perpetual lustings of the flesh against the spirit; whereby they are often foiled with temptations, and fall into many sins *26, are hindered in all their spiritual services *27, and their best works are imperfect and defiled in the sight of God *28.
