Could you please help me with the Bible?

The next "prophetic" event (on the prophecy calender) to occur is the rapture (or the "catching away") of the Lord's church, ie, all true christians. He will come in the clouds and the ones still on earth at this time will be caught up "to meet Him in the air." What it is saying is that a day is coming soon when millions will disappear suddenly and without any real explanation.
