My second use shall be to them that are dejected in their souls at the sight and sense of their sins.
First. Are they that are saved, saved by grace? Then they that would have their guilty consciences quieted, they must study the doctrine of grace.
It is Satan’s great design either to keep the sinner senseless of his sins, or if God makes him sensible of them, then to hide and keep from his thoughts the sweet doctrine of the grace of God, by which alone the conscience getteth health and cure; “for everlasting consolation, and good hope” is given “through grace” (1 Thess 2:16). How then shall the conscience of the burdened sinner by rightly quieted, if he perceiveth not the grace of God?
Study, therefore, this doctrine of the grace of God. Suppose thou hast a disease upon thee which is not to be cured but by such or such medicines, the first step to thy cure is to know the medicines. I am sure this is true as to the case in hand; the first step to the cure of a wounded conscience is for thee to know the grace of God, especially the grace of God as to justification from the curse in his sight.
A man under a wounded conscience naturally leaneth to the works of the law, and thinks God must be pacified by something that he should do, whereas the Word says, “I will have mercy and not sacrifice: for I am not come to call the righteous, but sinners to repentance” (Matt 9:13).
Wherefore thou must study the grace of God. “It is a good thing,” saith the apostle, “that the heart be established with grace”; thereby insinuating that there is no establishment in the soul that is right but by the knowledge of the grace of God (Heb 13:9).
I said, that when a man is wounded in his conscience, he naturally leaneth to the works of the law; wherefore thou must therefore be so much the more heedful to study the grace of God; yea, so to study it as rightly, not only in notion, but in thy practices, to distinguish it from the law. “The law was given by Moses, but grace and truth came by Jesus Christ” (John 1:17). Study it, I say, so as to distinguish it, and that, not only from the law, but from all those things that men blasphemously call this grace of God.
There are many things which men call the grace of God, that are not.
1. The light and knowledge that are in every man. 2. That natural willingness that is in man to be saved. 3. That power that is in man by nature to do something, as he thinketh, towards his own salvation.
I name these three; there are also many other which some will have entitled the grace of God. But do thou remember that the grace of God is his goodwill and great love to sinners in his Son Jesus Christ; “by the which” good “will we are sanctified, through the offering of the body of Jesus Christ once for all” (Heb 10:10).
