“Special faith in Christ is of the operation of the Spirit of God: he produces it by his mighty power in the soul; he enlightens the mind, reveals the object, brings near Christ, his righteousness and salvation, and enables the sensible sinner to look unto him, lay hold on him, and receive his as his Savior and Redeemer; hence he is called the Spirit of faith (2 Cor. 4:13); because he is the author of it, who begins and carries on, and will perform the work of faith with power: the principal use of which grace is to receive all from Christ, and give him the glory.
God has put this honor upon it, to constitute and appoint it to be the receiver-general of all the blessings of grace. It receives Christ himself as the Father’s free-gift; it receives out of the fulness of Christ, even grace for grace, or and abundance of it; it receives the blessing of righteousness from the Lord of justification; it receives the remission of sins through his blood, according to the gospel-declaration; it receives the adoption of children, in consequence of the way being opened for it through the redemption which is in Christ; it receives the inheritance among them that are sanctified, the right unto it, and the claim upon it; and to this post it is advanced, that all the glory might redound to the grace of God; it is of faith, that it might be by grace (Rom. 4:16): there are other uses of faith, and actings of it, which will be observed under the following head.” – John Gill
