He said, "I am the voice of one crying in the wilderness, 'Make straight the way of the Lord,' as Isaiah the prophet said."

 In 560 B.C. there was an Ephesian philosopher called Heraclitus whose basic idea was that everything is in a state of flux. Everything was changing from day to day and from moment to moment. His famous illustration was that it was impossible to step twice into the same river. You step into a river; you step out; you step in again; but you do not step into the same river, for the water has flowed on and it is a different river. To Heraclitus everything was like that, everything was in a constantly changing state of flux. But if that be so, why was life not complete chaos? How can there be any sense in a world where there was constant flux and change?
