“The Apostle Peter says that the first world was created out of water and perished by water. “Out of water” is also an image of the chaos of the physical mass, while “perished by water” is [an image] of the flood. And now the world is reserved unto fire…..The earth also and the works that are therein shall be burned up (II Peter 3:7-10). All the elements will melt. This present world will perish in a single instant. In an instant everything will change. And the sign of the Son of God will appear, that is, the sign of the Cross. The whole world, having willingly submitted to Antichrist, “will break out in lamentation,” Everything is finished. Antichrist is slain. The end of his kingdom, the end of the war with Christ. The end, and accountability for one’s whole life, an account to the True God.”
(St. John of San Francisco, homily)
