Ed, in mental health forums the concept that you are ONE of the witnesses is called "delusions of grandeur" It is a sign of impending or of psychosis. You should get checked out by a doctor before you go off the deep end.

We cannot know when Jesus will return, and looking at the signs, is something that has been happening since the 1st century. Everyone thinks the time they live in is special, and Jesus is returning now, because now is the worst/best time to come. I was just reading that in 17th century eschatology in Britain, the Baptists thought Jesus would return at the turn of the century. Remember, the point is not WHEN he returns, but "will he find faith on the earth?" Luke 18:8

Get your heart right, and you will be with Jesus no matter what or when it happens.
