The Sanctifying Influences of Faith

The outline of the scriptural doctrine on the subject of faith seems to be; FIRST, that men are justified by faith, and second, that, being justified, they live by faith. And accordingly it is said in one place, “being justified by faith, we have peace with God through our Lord Jesus Christ;” and in another, “the just shall live by faith.” So much has been said on the subject of justification by faith, it having been almost from the commencement of the christian era, a leading subject of discussion, that it has not seemed to us necessary to occupy much time with it. And accordingly it will be noticed, that ... the attention of the reader is designed to be directed, not so much to the justifying, as to the sanctifying influences of faith. 

A man may make the most decided efforts and may resort to all methods, to subdue and to bring back his fallen nature within the limits of God’s appointment and law; but it will avail nothing without faith. Without faith, (not merely that faith which justifies but that which sanctifies,) the Appetites, which are not too low and degraded to become purified and holy, always exhibit an action, which is disorderly, uncontrolled, and evil. Without faith, the Propensive principles, which may be regarded higher in their position and influence than the Appetites, although lower than the affections, run into various forms and degrees of unauthorized irregularity and excess. And we may add, without going into particulars, that without faith in God, and without faith in Christ as the mediator between God and man, man’s whole moral nature will inevitably show itself, as it always has shown itself, rebellious, perverse, and evil.
