And this grace is farther said to be wrought in the heart of a sinner, by the Spirit. We have before considered effectual calling, as a work of divine power, and proved, that the Spirit is the author of it;[64] and that they, who are effectually called, are enabled to accept of, and embrace the grace offered in the gospel; from whence it is evident, that faith is the fruit and consequence of our effectual calling; and therefore it must be a work of the almighty power and grace of the Holy Spirit. And, this it farther appears to be, from that account which we have thereof in several scriptures: thus the apostle Peter, describing those he writes to, as having _obtained like precious faith, through the righteousness of God and our Saviour Jesus Christ_; and also as having _all things that pertain unto godliness_, in which faith is certainly included, he ascribes this to the _divine power_, 2 Pet. i. 1. compared with the 3rd verse. And elsewhere we read _of the exceeding greatness of the power_ of God exerted _in them that believe_, Eph. i. 19. And when the work of faith is carried on, or fulfilled in the souls of those in whom it was begun, it is considered as an effect of the same power, 2 Thess. i. 11. And, as all that grace, which is the effect of divine power, is ascribed to the Holy Ghost, when he is said hereby, as acting in subserviency to the Father and Son, to demonstrate his Personal glory: so the work of faith, in this respect, is represented as his work; upon which account he is called the _Spirit of faith_, 2 Cor, iv. 13. But that which we shall more particularly consider is, that this grace of faith is wrought by the instrumentality of the word. We have before observed, that the principle of grace, implanted in regeneration, is the immediate effect of the divine power, without the instrumentality of the word; but when the Spirit works faith, and all other graces, which proceed from that principle, then he makes use of the word: thus the apostle says, _Faith cometh by hearing, and hearing by the word of God_, Rom. x. 17. As it is necessary, in order to our seeing any object, that the eye be rightly disposed and fitted for sight, and the object presented to it: so there are two things necessary to faith, namely, the soul’s being changed, renewed, quickened, and so prepared to act this grace; and the objects being presented to it, about which it is to be conversant; which latter is done by the word of God: so that the soul is first internally disposed to receive what God is pleased to reveal relating to the way of salvation by Jesus Christ before it believes; and this revelation is contained in the gospel, which is adapted to the various acts of faith, as before described.
