The whole world is not watching for all the events of the Great Tribulation Period, which will destroy world civilization and see the death of most people on planet earth.  They will be caught in a snare.  Jesus, however, taught that an individual needs to pray always to escape all these things that shall come to pass.  Deliverance is only through the Gospel message, which is the death, burial, and resurrection of Jesus Christ.  Right now, there's still hope for every person on this planet, but there's coming a time when it will be too late.
