NASA is tracking nearly 1,400 asteroids that have the potential to destroy the Earth.
Rev 16:21 And there fell upon men a great hail out of heaven, every stone about the weight of a talent: and men blasphemed God because of the plague of the hail; for the plague thereof was exceeding great.
Although that particular day is not here yet, asteroids will hit earth for sure at a later point in time, and no one will be able to do anything about it. How many will hit before that day God pours out his wrath on the people of this world for disobedience is unknown. All any of us can do is be ready to meet him to escape the things coming upon the world.
