Christ is the food of our souls, He and His work are meant to nourish
our whole being. He is the object for all our nature.
The Sacrifice must be incorporated with us. It is not enough that it be
offered, it must also be partaken of.
Now the Sacrifice is eaten by faith, and by occupation with it of each
part of our being, according to its own proper action. Through love,
obedience, hope, desire, we may all feed on Jesus.
The Lord's Supper presents the same thoughts, under similar symbols, as
Isaiah expressed in his prophecy.
Symbolically we feast on the sacrifice when we eat the Bread which is
the Body broken for us. But the true eating of the true sacrifice is by
faith. _Crede et manducasti_--Believe, and thou hast eaten.
