In Daniel 12:1 it says: "And at that time shall Michael stand up, the great prince which standeth for the children of thy people; and there shall be a time of trouble, such as never was since there was a nation even to that same time: and at that time thy people shall be delivered, everyone that shall be found written in the Book."

But, if it is looked at with a magnifying glass, it can be seen that there are divisions. If one stands on railroad tracks and looks far down the tracks, in the distance they seem to come together and make one track.
