I. In the first place, we would observe that _sacrifice is the basis of worship_. Acceptable worship to God must be based on a sacrifice acceptable to Him. Man being in himself guilty and unclean, he needs a sacrifice to remove his guilt, cleanse him from his defilements, and fit him for the holy presence of God. "Without shedding of blood is no remission;" and without remission, and the _knowledge_ of remission, there can be no happy worship,--no real, hearty praise, adoration, and thanksgiving. Going to what is called "a place of worship," and worshiping God, are widely different things. God is holy, and man must approach Him in His own way, and according to what He is. As Moses said unto Aaron on the solemn occasion of the sin of Nadab and Abihu, "This is it that the Lord spake, saying, '_I will be sanctified in them that come nigh Me_, and before all the people I will be glorified.'" The Lord alone could give directions as to how the people were to draw nigh unto Him: this is the great subject of the book of Leviticus. The "Notes" on the first seven and the sixteenth chapters will give the reader a very full and interesting view of the ordinance of sacrifice, and the character of Jewish worship. It was on the ground of offered and accepted sacrifice that the children of Israel were constituted the worshiping people of God. It is on the same ground, namely, offered and accepted sacrifice, that believers in Jesus are constituted the worshiping people of God now. (Read carefully Lev. xvi; Heb. ix, x.) They have taken Israel's place, but after a much higher order, whether we look at the sacrifice, the priest, or the place of worship. The contrast between them is great, and strongly marked in Scripture, especially in the epistle to the Hebrews. The Jewish sacrifices never reached the _conscience_ of the offerer, and the Jewish priest never could pronounce him "clean every whit." The gifts and sacrifices which were offered under the law, as the apostle tells us, "could not make him that did the service perfect, as pertaining to the conscience." The conscience, observe, always being the _reflection_ of the sacrifice, it could not be perfect, seeing the sacrifice was not perfect; "for it is not possible that the blood of bulls and of goats should take away sins." Hence, Jewish worship was connected with inefficient sacrifices, a burdensome ritual, and an unpurged conscience, which gendered in the worshiper a spirit of bondage and fear.
