He that justifieth the wicked, and he that condemneth the just, both are abominable before God.
So as a man draws closer to God, and increasingly aligns his mind, thinking and will with God's will, wouldn't his stomach start to turn when he sees and hears people praising wickedness and condemning good people?
If we know and love God, we should increasingly love what God loves, and hate what God hates. Sin, especially abominable sins, should turn our stomachs.
And it should drive any friend of God INSANE the degree to which the modern world is calling good "evil" and evil "good", and calling lies "truth" and truth "lies".
