But God's justice is not fairness. God's justice has its standard in true and perfect righteousness. Humanity that cannot understand true righteousness, being fallen and depraved, cannot attempt to qualify the parameters of justice.
I appreciate what Walther Luethi, a German pastor wrote:
"If the time should ever come (for these things are conceivable nowadays) when we should succeed in demonstrating that black is white and white black, that good is evil and evil good, if we should ever be successful in invalidating the fundamental moral principles of the universe, so that sin were no longer hated and everyone took a fancy to evil, then there would still be a stronghold where evil would be hated, and that is heaven. And there would still be one who has sworn to fight the evil in the world to the last drop of his blood, and that is God, whose "wrath is revealed from heaven against all ungodliness and wickedness of men."
It is to the God who hates evil, who is true righteousness, who is an all-consuming fire, and who is the just judge of all the earth that dispenses perfect justice.
Lest this make us squirm, let this make us squirm even more:
"God does not condemn people for failing to do what they did not even know they should do, but rather for failing to follow the revelation they do have." James Montgomery Boice
