It is sobering, my friend. You caught the Biblical allusion, not as whimsical as frost's tongue-in-cheek poem:

Some say the world will end in fire,
Some say in ice.
From what I’ve tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.
