II For convincing a man of righteousness by the law, consider Gal. iii. 10.
For as many as are of the works of the law are under the curse: for it is written, Cursed is every one that continueth not in all things which are written in the book of the law to do them.
Here the apostle teacheth us three things:
1. That, by reason of our natural sinfulness, the impossibility of any man's being justified by the law is so certain, that whosoever do seek justification by the works of the law, are liable to the curse of God for breaking of the law; "For as many as are of the works of the law are under the curse," saith he.
2. That, unto the perfect fulfilling of the law, the keeping of one or two of the precepts, or doing of some, or of all duties (if it were possible) for a time, is not sufficient; for the law requireth, that "a man continue in all things which are written in the book of the law to do them."
3. That, because no man can come up to this perfection, every man by nature is under the curse; for the law saith, "Cursed is every one that continueth not in all things which are written in the book of the law to do them."
Now, to be under the curse, comprehendeth all the displeasure of God, with the danger of the breaking forth more and more of his wrath upon soul and body, both in this life, and after death perpetually, if grace do not prevent the full execution thereof.
Hence let every man reason thus:
Whosoever, according to the covenant of works, is liable to the curse of God for breaking the law, times and ways out of number, cannot be justified, or find righteousness by the works of the law :
But I, (may every man say,) according to the covenant of works, am liable to the curse of God, for breaking the law times and ways without number:
Therefore, I cannot be justified, or have righteousness by the works of the law."
Thus may a man be convinced of righteousness, that it is not to be had by his own works, or by the law.
