Christ In The Old Testament

The famous eunuch from Ethiopia was reading from the scroll of Isaiah when 

  Philip was sent to him. Within only a few hours, the eunuch asked to be 

  baptized. He had learned about Christ from Philip’s explanation of Isaiah’s 

  prophecies. How was this possible? Could the eunuch have received Christ as 

  his Savior, and been saved by grace, through understanding what Isaiah wrote? 

  Isn’t the Old Testament "done away"? Is the knowledge necessary for salvation 

  to be found in the Old Testament? Read, in your own Bible, the astonishing 

  truth!
