No. Faith is an evangelical grace:2. Faith is a work/duty
"I. The grace of faith, whereby the elect are enabled to believe to the saving of their souls, is the work of the Spirit of Christ in their hearts; and is ordinarily wrought by the ministry of the Word: by which also, and by the administration of the sacraments, and prayer, it is increased and strengthened."
The WCF says that “it is every man’s duty to endeavor to repent of his particular sins, particularly” (WCF 15.5). Such repentance is repentance unto life as is the title of chapter 15. Faith and repentance are called both a “requirement” (WCF 7.3) for salvation and a “condition” (WLC 32) of salvation. In the Westminster description of the law, both “condition” (WCF 7.2) and “require” (WLC 99) are similarly used, thus shedding light to Charles Hodge’s words which state that the response to the call of the gospel “of necessity binds all those who are in the condition which the plan contemplates… [and] is in this respect analogous to the moral law.” This is not neonomian language as has been suggested, but simply Hodge is recognizing the similarities that the Westminster finds and acknowledges that man has this duty, namely to savingly repent.
I don't know if you realize how much you are skipping over to get to 15.5. The very first clause of WCF 15 states:
I. Repentance unto life is an evangelical grace...
15.6 states that every man is bound to repent but this is clearly connected to those who have received this evangelical grace and cannot be generalized to all men as you have erroneously inferred.
What you call duty/work the Confessions call evangelical graces. You have not established some major premises in your ignoring of the Standards on this point.
