At the beginning of the Millennial Era, Christ will return to the earth. This event will mark the end of the mortal probation of this earth. The wicked will be removed from the earth and the righteous will be caught up in a cloud while the earth is cleansed. While no man knows exactly when Christ will come for the second time, He has given us signs to watch for that indicate the time is drawing near (Matt. 24; JS—M 1).
