Albert Barnes Commentary Revelation 6:17

"for the great day of their wrath is come; and who is able to stand?" — Revelation 6:17 (ASV)

For the great day of his wrath is come. The threatening judgments would be so severe and awful that they would suppose that the end of the world was coming.

And who shall be able to stand? To stand before him, or to withstand his judgments (Psalms 76:7).
