VIII. OF FREE-WILL
The condition of man after the fall of Adam is such that he can not turn and prepare himself, by his own natural strength and works, to faith and calling upon God; wherefore we have no power to do good works, pleasant and acceptable to God, without the grace of God by Christ preventing us, that we may have a good will, and working with us, when we have that good will.
IX. OF THE JUSTIFICATION OF MAN
We are accounted righteous before God, only for the merit of our Lord and Savior Jesus Christ, by faith, and not for our own works or deservings; wherefore, that we are justified by faith only, is a most wholesome doctrine, and very full of comfort.
X. OF GOOD WORKS
Although good works, which are the fruits of faith and follow after justification, cannot put away our sins, and endure the severity of God's judgment; yet are they pleasing and acceptable to God in Christ, and spring out of a true and lively faith, insomuch that by them a lively faith may be as evidently known as a tree discerned by its fruit.
XI. OF WORKS OF SUPEREROGATION
Voluntary works, besides over and above God's commandments, which are called works of supererogation, cannot be taught without arrogancy and impiety. For by them men do declare that they do not only render unto God as much as they are bound to do, but that they do more for his sake than of bounded duty is required; whereas Christ saith plainly, When ye have done all that is commanded you, say, We are unprofitable servants.
