"In the Old Testament are two types of sacrifices:  the first was called the

early morning sacrifice; thereby is shown that we should offer unto Christ,

not oxen or cattle, but ourselves, acknowledging God's gifts, corporal and

spiritual, temporal and eternal, and giving him thanks for them.  Secondly, the evening sacrifice;  whereby is signified that a

Christian should offer a broken, humble, and a contrite heart, consider his necessities and dangers, both corporal and

spiritual, and call upon God for help."

-Martin Luther-
