The language of the apostle confirms this view: 'What the law could not do, in that it was weak through the flesh, God, sending his own Son in the likeness of sinful flesh, and for sin, condemned sin in the flesh'--that is, the law, although it had power to show to the mind the evil and the guilt of sin, had no power to produce in the heart an aversion to it; but Christ coming in the body, and dying for sin, in that way reaches man's moral feelings, and creates a sentiment of condemnation of, or aversion to, sin in the heart of every believer. A feeling cannot be manifested by intellect or will. A communication of knowledge, or law, does not manifest feeling so that it produces feeling in others. The moral feelings of God were manifested by the sacrifice of Christ; and that manifestation, through the flesh, affects the moral feelings of man, assimilates them to God, and produces an aversion to sin--the abominable thing which God hates. Blessed faith! which, while it purifies the heart, works by the sweet influence of love in accomplishing the believer's sanctification. _2. The influence of faith in Christ upon the moral sense, or conscience of believers._--To a mind endowed with the higher qualities of reason, there can be no more interesting thought than that noticed in a previous demonstration; which was, that a man's conscience is guided by his faith. Conscience is the highest moral faculty, or rather the governing moral power of the soul; and this governing faculty is regulated and controlled by faith. Man's conscience always follows his religious belief, and changes with it, and grows weak or strong with it. Now, as God has so constituted the world that the affections, and likewise the conscience, are affected and controlled by faith; and the purity of the one, and the integrity of the other, and the activity of both, depend upon what man believes: this being true, no mind can avoid the conviction, that the principle of FAITH, which Christ has laid at the foundation of the Christian system, is from the nature of things, the only principle through the operation of which man's moral powers can be brought into happy, harmonious, and perfect activity. But this happy effect, as has been shown, can be produced only by faith in the truth; and besides, it is an intuition of reason, that God certainly would not make the soul so that its moral powers would be controlled by faith, and then cause that faith in falsehood should perfect and make happy those powers. Such a supposition would be a violation of reason, as well as an impiety. In searching, therefore, for the answer to the inquiry, What is truth? as it concerns the spiritual interests of man, the direct process of solution would be, to inquire what effect certain facts, or supposed facts, would have upon the moral disposition and moral powers of the soul; and that faith which quickens and rectifies those powers, as we have noticed, is necessarily truth.
