I guess the question, incidentally, is not put correctly for it is an instance of the unintentional "complex question" fallacy when two unreal opportunities are offered for an answer, like in an instance: "Has or has not Donald Trump ceased eating new born babes?" - in both possibilities of the answer, "yes" or "no", an unreal thing obtains that Donald Trump has in fact eaten new born babes.
Here also. If the question is: "what does an expression 'fear of enemy' mean? a) fear that enemy has; or b) our fear imparted on us by the enemy?" Here we have a legitimate and clear "either or" question, for both cannot be implied simultaneously.
But here, in the mentioned passage of the Apocalypse, a completely different situation can be at stake! - Namely, here we can have a reality that is impossible without reciprocality and mutuality. Like in a sentence: "A synergy of Volkswagen saved Audi from bankruptcy", here it is grammatically unclear whether it is activity of Volkswagen that saved Audi, or activity of Audi with Volkswagen saved it; however, semantically it is clear that both are simultaneously, for the reality of "synergy" entails only mutual activity analytically, for "syn-ergeia" per definition means "mutual-activity".
I guess, the faith in Christ is also a mutual, synergic activity both on the part of God and on the part of man, for God Himself does not have faith, so we cannot even say "faith of God" in the sense of God possessing something without us and then giving to us, like I possess my Beatles' disc and give it to you who do not possess it; no! God does not have faith without us, and even that faith which He puts in us is not possessed by Him without this very putting! And furthermore, it is indeed God who puts faith in us, but this "put" thing will not remain put in us unless we co-act with it, with the very presence of divine grace in us. So extremely difficult to express the relationship of God's grace and faith that He puts in us! But let me try to express it in just next paragraph, for I feel I can do it in this very moment, for I hold it like a tail of a lizard that is about to escape in bushes, and moreover, this tail can be that of a dinosaur also.
In difference from faith, we can say that God possesses grace without even us, for grace is His uncreated feature, that He had before even the world was created. Thus, what is then faith that He puts in us? This also must be grace, for He - I mean without the created world - possesses nothing to give to us unless His grace. Thus, is faith - grace? Yes and no. Faith is grace in the sense that it is invitational grace that influences our intellectual nature to covet it for its own eternal benefit, which benefit is more beautifully and tastily called "bliss". Just like a smell, a chill and a comely form of an ice cream in hot summer invites us for a (temporary and transient) bliss even before we smack it in our mouths the very first time; similarly, the beautiful and supra-humanly virtuous behavior of the Lord Jesus Christ, His ability and act of forgiving with love even his murderers at the very moment of being sadistically murdered, arises in us an awe and a dread, but also a strong impulse of credibility that He is the one whom all mankind expects as giving the best destiny to mankind, and a strong impulse to believe also in His words that this destiny, if His commandments are followed, will last eternally. Thus, those deeds and those words touching our hearts and minds are already invitational grace from Him, like the smell, form and chill of an ice cream in a scorching sunny summer day, and as we then, in case of yet untasted ice cream make an initiative of faith and put it in our mouths, so also, after being touched by the invitational grace, we make an initiative of faith and get baptized, start to go to church, pray, receive holy communion and grow more fully in faith, just like a glutton once having tasted ice cream will then discover the entire world of ice creams of hundreds of different nuances and gamut of taste. But a glutton will destroy eventually his health, while a glutton of grace will gradually destroy his sinfulness and become an inhabitant of the Eternal Kingdom of Christ.
But again, to return to the OP main topic: the offered question's grammatical correctness is defied by its semantical wrongness, for "faith" is a synergic thing, co-acting thing on the part of both God/Christ and men, and thus cannot be even regarded in separation.
