There is no part of God’s wrath that can lead one to doubt. His anger is pure, unadulterated anger and harbors no other intentions or goals. The reason for His anger is pure, blameless and above criticism. It is a natural revelation and display of His holy substance; it is something that none of the creation possess. This is a part of God’s unique righteous disposition, and it is also a striking difference between the respective substances of and His creation.
