Question 9. But doesn't God do us an injustice by requiring in the law what we are unable to do?
Answer. No. God created human beings with the ability to keep the law. They, however, tempted by the devil, in deliberate disobedience, robbed themselves and all their descendants of these gifts.
Answer. Certainly not. God is terribly angry about the sin we are born with as well as the sins we personally commit. As a just judge God punishes them now and in eternity. God has declared: "Cursed is everyone who does not observe and obey all the things written in the book of the law."
