That we may therefore, in some weak measure, through the help of this light and grace, propose some things to clear up this great and necessary truth, we shall first speak a little to it in the general, and then come to clear up the matter more particularly.

Before we speak of the matter in general, it would be remembered, 1.  That the person who only is in case to make use of Christ for sanctification, is one that hath made use of him already for righteousness and justification.  For one who is a stranger to Christ, and is living in nature, hath no access to Christ for sanctification.  He must be a believer, and within the covenant, ere he can make use of the grounds of sanctification laid down in the covenant.  One must first be united to Christ, and justified by faith in him, before he can draw any virtue from him for perfecting holiness.  He must first be in him, before he can grow up in him, or bring forth fruit in him.  And therefore the first thing that souls would go about, should be to get an union made up with Christ, and be clothed with his righteousness by faith; and then they have a right to all his benefits. First, they should labour to get their state changed from enmity to peace and reconciliation with God, through faith in Jesus.

Yet, next, it would be observed, that when it is said, that one must be a believer before he can go to Christ, and make use of him for holiness and sanctification, it is not so understood and said, that one must know, that indeed he is justified by faith, before he can make any use of Christ for sanctification.  One may be justified, and a believer, yea, and growing in grace through Jesus Christ, and so actually improving the grounds of sanctification, and making use of Christ for this end, and allowed thereunto, and yet win to no certainty of his union with Christ, of his justification through faith in him, nor of his faith.

But, thirdly, if it be said, How can a soul with confidence approach to Christ, for use-making of him, in reference to sanctification, that is, still doubting of his state and regeneration?

I answer, It is true, a clear sight of our interest in Christ by faith, would be a great encouragement to our confident approaching to, and use-making of him, in all things; and this consideration should move all to a more earnest search and study of the marks and evidences of their interest; a good help whereunto they will find in the forementioned book.  I shall only say this here, That if the soul have an earnest desire to be sanctified wholly, and to have on the image of God, that he may glorify him, and panteth after holiness as for life, that he may look like him that is holy, and maketh this his work and study; sorrowing at nothing more than at his shortcoming; crying out and longing for the day when he shall be delivered from a body of death, and have the old man wholly crucified; he needeth not question his interest
