Lord's Day 4

Question & Answer 9

Q: But doesn't God do us an injustice by requiring in his law what we are unable to do?

A: No, God created humans with the ability to keep the law.1
They, however, tempted by the devil,2
in reckless disobedience,3
robbed themselves and all their descendants of these gifts.4

Question & Answer 10

Q: Will God permit such disobedience and rebellion to go unpunished?

A: Certainly not.
He is terribly angry
about the sin we are born with
as well as the sins we personally commit.
As a just judge
he punishes them now and in eternity.1
He has declared:
"Cursed is everyone who does not continue to do
everything written in the Book of the Law."2

Q: But isn't God also merciful?

A: God is certainly merciful,1
but he is also just.2
His justice demands
that sin, committed against his supreme majesty,
be punished with the supreme penalty-
eternal punishment of body and soul.3
