Heidelberg Catechism – Lord’s Day 4
Q. Is not God unjust in requiring of man in his Law what he cannot do?
A. No, for God so created man that he could do it. But man, upon the instigation of the devil, by deliberate disobedience, has cheated himself and all his descendants out of these gifts.
Q. Will God let man get by with such disobedience and defection?
A. Certainly not, for the wrath of God is revealed from heaven, both against our inborn sinfulness and our actual sins, and he will punish them according to his righteous judgment in time and in eternity, as he has declared: “Cursed be everyone who does not abide by all things written in the book of the Law, and do them.”
Q. But is God not also merciful?
A. God is indeed merciful and gracious, but he is also righteous. It is his righteousness which requires that sin committed against the supreme majesty of God be punished with extreme, that is, with eternal punishment of body and soul.
