A sign and an omen from God warning of things which must shortly come to pass.  Lightning strikes the cross atop Saint Peter's Dome hours after Pope Benedict XVI resigns. See video here.  Days later, a meteorite strikes Russia, injuring more that 1,000 people.  The next day, a fireball streaks across the night sky in San Francisco.  Three signs in one week but will the people heed God's warning of judgment to come?  "And I will shew wonders in the heaven above, and signs on the earth beneath: blood and fire, and vapour of smoke" (Acts 2:19).
