In all the history of the world Jesus emerges as the only "expected" person. No one was looking for such a person as Julius Caesar, or Napoleon, or Washington, or Lincoln to appear at the time and place that they did appear. No other person has had his course foretold or his work laid out for him centuriesbefore he was born. But the coming of the Messiah had been predicted for centuries. In fact, the firstpromise of His coming was given to Adam and Eve soon after their fall into sin. As time went on various details concerning His Person and work were revealed through the prophets; and at the time Jesus was born there was a general expectation through the Jewish world that the Messiah was soon to appear, even the manner of His birth and the town in which it would occur having been clearly indicated.
