The Cross is the end of the sacrificial system, but not of its meaning. If we isolate the Cross from the long history of sacrifices, we tend to stress only what Christ did for us, the rightly finished work. If we approach the atonement with the meaning of sacrifice in mind, we are enabled to recognize what Christ now expects of us.
