God must demonstrate the strength of his anger in the way he judges the world. It is not simply enough to obliterate the wicked in a moment, because even his judgment carries lessons in it, which teach us about the effects of sin on us.
These transformation are all signals of the power of God’s wrath. He made life in the first place, and he prepared a home for man to live in full of good things, but if we oppose him and disregard his laws, he will turn against us with the utmost force.
