Simplify a passage
Please explain the following passage in simple words. I am having difficulty understanding the idea of Messianic time.
"Historicism contents itself with establishing a causal connection between various moments in
history. But no fact that is a cause is for that very reason historical. It became historical
posthumously, as it were, though events that may be separated from it by thousands of years. A
historian who takes this as his point of departure stops telling the sequence of events like the
beads of a rosary. Instead, he grasps the constellation which his own era has formed witha
definite earlier one. Thus he establishes a conception of the present as the 'time of the now'
which is shot through with chips of Messianic time."
