...unfortunately, that’s how some people view and use the Old Testament. They see Christ emerge from the picture at the end of Old Testament history (and that’s good), but they do not see him in all the little pictures. ...For example, some see all the Old Testament priests as pointing forwards to Christ’s priestly work; and they do that. Some see all the Old Testament kings as pointing forwards to Christ as King of all kings; and He is that. But is Christ only seen at the end of these long lines of priests and kings? Does He only emerge from the picture when we look back with New Testament eyes? Sometimes that’s the impression that’s given. But where does that leave Old Testament believers? Did they simply put their trust in Moses' sacrifices, Aaron’s priesthood, and David’s monarchy? No! By faith they saw the coming Messiah pictured in the Mosaic sacrifices, Aaron’s priesthood, and David’s kingdom. They saw Christ in the small pictures. True, they only saw Him in shadow form; but shadow implies at least some light, doesn’t it!
