Sacrifices

Because the Commandments teach us so much about our sins, God’s people in the Old Testament were very aware of their sins.  For that reason there is also a huge variety of sacrifices in the Old Testament.  Just from the first 6 chapters of Leviticus there are:

    Burnt Offerings
    Grain Offerings
    Fellowship Offerings
    Sin Offerings, and 
    Guilt Offerings.

There were the daily sacrifices, the sacrifice of the Lamb at Passover (see Exodus 12), the Scapegoat (on whom the sins of the nation were placed and who then was driven out of the camp – so the Bible says Jesus had to go outside the city to be crucified), and many more.

All these sacrifices point to Jesus.  They tell us how Jesus Christ has taken every kind of our sins on Himself and died in our place.
