God, by the very perfection of His moral nature, cannot but be angry at sin – not only because of its destructiveness to humans, but, more important, because of its assault on His divine majesty. This is not the mere petulance of an offended deity because His commands are not obeyed. It is rather the necessary response of God to uphold His moral authority in His universe. And though God’s wrath does not contain the sinful emotions associated with human wrath, it does contain a fierce intensity arising from His settled opposition to sin and His determination to punish it to the utmost.
