Counter-Arguments

The strongest case that this verse does not belong in this theme.

Destruction at Coming

The verse speaks of judgment in the present tense ("I am come"), not specifically at a future return. The "blindness" mentioned is spiritual, not necessarily a physical destruction of the wicked.
