Apart from the regenerating grace of God, we hate him fully, resist him fully, are "children of wrath by nature" (Ephesians 2), "dead" (Ephesians 2), "enemies" (Romans 5), who not only cannot "enter" the kingdom of God, we cannot even "see" it. We "must be born again from above" (John 2). We resist the grace of God until he says "enough," and calls us from the tomb as Jesus did to Lazarus--creating, with the call, both the desire and the ability to obey it.
The only reason we ever "want" to obey him is evidence of his effectual grace (Romans 7). The point of the quote is that our will cannot stop God's will.
That said, I echo the struggle you mentioned--but that is a Romans 7-like struggle that only believers experience, and it is the struggle of sanctification, not justification.

Q. 70. What is justification?
A. Justification is an **act** of God’s free grace unto sinners, in which he pardons all their sins, accepts and accounts their persons righteous in his sight; not for anything wrought in them, or done by them, but only for the perfect obedience and full satisfaction of Christ, by God imputed to them, and received by faith alone.
Q. 75. What is sanctification?
A. Sanctification is a **work** of God’s grace, whereby they whom God hath, before the foundation of the world, chosen to be holy, are in time, through the powerful operation of his Spirit applying the death and resurrection of Christ unto them, renewed in their whole man after the image of God; having the seeds of repentance unto life, and all other saving graces, put into their hearts, and those graces so stirred up, increased, and strengthened, as that they more and more die unto sin, and rise unto newness of life.
Q. 77. Wherein do justification and sanctification differ?
A. Although sanctification be inseparably joined with justification, yet they differ, in that God in justification **imputes** the righteousness of Christ; in sanctification his Spirit **infuses** grace, and enables to the exercise thereof; in the former, sin is **pardoned**; in the other, it is **subdued**: the one doth equally free all believers from the revenging wrath of God, and that perfectly in this life, that they never fall into condemnation; the other is neither equal in all, nor in this life perfect in any, but growing up to perfection.
