In one sense, of course, nothing can compare to the great Day of the Lord. Nothing compares to it, and yet Scripture repeatedly compares things to it. But the Bible does this in such a way as to show that nothing can compare, which is what gives the comparisons such force.
“The high places also of Aven, the sin of Israel, shall be destroyed: The thorn and the thistle shall come up on their altars; And they shall say to the mountains, Cover us; And to the hills, Fall on us” (Hos. 10:8; cf. Luke 23:30).
So if you want one sort of image for the Day of Judgment, here in the Pacific Northwest we have multiple forest fires to choose from. The flames can get 300 feet high. Use your imagination.
In another sense, there is second aspect to the Day of Judgment that seems much quieter and less lurid, and yet is far more terrifying. Bu it is only actually terrifying if you think about it, which is what these Planned Parenthood videos are making us all do. These videos are a tiny taste of what it is going to be like when every mouth is stopped, and the whole world is guilty before God (Rom. 3:19).
The coldest things about these videos is the ordinary hardness of heart shown in them — in the jokes, in the throw away lines.
