God's characteristic way of teaching Israel in the Old Testament was by means of pictures and models. One such type (as we call these illustrations now) was the Passover. Celebrated annually, this feast was intended to remind Israel of the past and to portray God's plan of salvation eventually to be enacted at Calvary.
1. THE NEED FOR REDEMPTION
(Israel was in the house of bondage and under sentence of death.)
2. THE NATURE OF REDEMPTION
(It was centered in the lamb.)
a. How the lamb was selected
b. How the lamb was slain
c. How the lamb was sufficient
3. THE NEGLECT OF REDEMPTION
(This meant death when the judgment angel passed through the land.)
NOTE: There is a progression in God's revelation of the truth concerning the Lamb. In connection with Cain and Abel it was a lamb for a man; at the Passover it was a lamb for a house; in connection with the evening and morning sacrifice it was a lamb for a nation; when Christ came it was a Lamb for the world. Note, in connection with the Passover, this additional progression--"A lamb, the lamb, your lamb." Note, too, that sometimes a house was too little for a lamb but that the lamb was never too little for the house.
