Here we do not assert the sufficiency thereof, exclusive of the aids of divine grace, so as to oppose the word to the Spirit: therefore it is said, in this answer, that the word and Spirit of God alone can reveal him to men sufficiently to their salvation. The word is a sufficient rule, so that we need no other to be a standard of our faith, and to direct us in the way to eternal life; but it is the Spirit that enables us to regard, understand, and apply this rule, and to walk according to it: these two are not to be separated; the Spirit doth not save any without the word,[14] and the word is not effectual to salvation, unless made so by the Spirit. That nothing short of scripture-revelation is sufficient to salvation, will appear, if we compare it with the natural knowledge we have of God. For, 1. Though the light of nature shews us that there is a God, it doth not fully display his perfections, so as they are manifested in scripture, wherein God is beheld in the face of Christ. 2. Neither doth it discover any thing of the doctrine of a Trinity of persons in the divine essence, who are equally the object of faith: nor doth it give us any intimation of Christ, as the Lord our righteousness, in whom we obtain forgiveness of sins: this is known only by scripture-revelation; therefore, since this is necessary to salvation, we are bound to conclude that the scripture alone is sufficient to lead to it. 3. The light of nature suggests, it is true, that God is to be worshipped; but there is an instituted way of worshipping him, which depends wholly on divine revelation; and since this is necessary, it proves the necessity of scripture. 4. There is no salvation without communion with God; or he that does not enjoy him here, shall not enjoy him for ever hereafter. Now the enjoyment of God is what we attain by faith, which is founded on scripture. Thus the apostle says, 1 John i. 3. _That which we have seen and heard, declare we unto you, that ye also may have fellowship with us; and truly our fellowship is with the Father, and with his son Jesus Christ._ But since it is one thing to say, that the knowledge of God, which is derived from scripture, is sufficient to salvation in an objective way; that is, that it is a sufficient rule to lead us to salvation, and another thing to say, that it is made effectual thereunto: we are now to inquire when it is made so. In answer to which, let us consider, that the doctrines contained in scripture are made effectual to salvation; not by all the skill or wisdom of men representing them in their truest light, nor by all the power of reasoning, which we are capable of, without the aids of divine grace, but they are made effectual by the Spirit; and this he does,
