2.What is it that the Law of Moses cannot do?

It cannot, by the continual animal sacrifices, make perfect the people who are trying to draw near to God through the sacrifices.

The sin and trespass offerings, the ashes of the red heifer, the bull and goats on the Day of Atonement, can never make perfect those who are attempting to satisfy and please God by these means.

To be perfect, in the sense emphasized here, is to be able to live without displeasing God—to be free from all sin and rebellion against God.

The inference is that the blood of Christ can make us perfect.

The need for blood to wash away our sins shows us that God is different from us. If we were God we would not require the shedding of blood in order to be satisfied. The blood of bulls and goats flowed by the thousands of gallons each year in order to satisfy God’s justice. We can understand from this that God is not altogether like us, although Christ lived as a man among us.
