Lord’s Day 4: Answering objections about God’s justice in dealing with sin (Questions 9-11)
Question 9: BUT DOESN’T GOD DO US AN INJUSTICE BY REQUIRING IN HIS LAW WHAT WE ARE UNABLE TO DO?
Question 10: WILL GOD PERMIT SUCH DISOBEDIENCE AND REBELLION TO GO UNPUNISHED?
God punishes sin most severely, justly, and certainly. He punishes it most severely, that is, with present and eternal punishment, on account of its enormity and greatness, because it is an offence against the infinite good. Most justly, because every sin, even the smallest transgression, is a violation of the law of God; and, therefore, according to the order of divine justice, deserves eternal punishment and banishment from God. Most certainly, because God is true, and does not change the sentence which the law denounces: “Cursed is he that continueth not in all things written in the book of the law to do them.” (Gal. 3:6.)
Question 11: BUT ISN’T GOD ALSO MERCIFUL?
all sins, even the smallest, deserve eternal punishment, because all offend the infinite and eternal good.
Every crime is great, and deserving of punishment in proportion to the majesty of him against whom it is committed.
The reason which makes this form of punishment necessary is evident from this: that sin which is committed against God, who is infinitely good, demands an infinite punishment and satisfaction, which could not be rendered by the afflictions which are incident merely to this life. This would not satisfy the infinite and eternal justice of God.
