The Peace Offering was to be offered with unleavened cakes mixed with oil. If it was to be offered as a thanksgiving, then the flesh of the sacrifice was to be eaten on the same day it was offered. If it was offered as a vow or voluntary offering, then it could be eaten over two days. Any left on the third day must be burned with fire. If any of the flesh touches any unclean thing or person, it should not be eaten. Unclean persons who eat of the sacrifice shall be cut off from their people.
The second law said that no fat or blood should be eaten. The person who does so would be cut off from his people as well.
The Peace Offering Law raises again the principle of the unclean. What is offered to God cannot be mingled with the unclean. We must offer to God our gifts, talents, money, etc. that are consecrated and holy, and fully dedicated to the service of the Lord.
The law of blood and fat reminds us of the limitations which God places upon us. Aside from the connection between blood and life, there is the simple fact that sometimes God draws lines that show us the limits of which He approves. Too often, we feel that grace simply gives us the right to do anything we desire. The Scripture plainly says, “4 Delight yourself also in the Lord, And He shall give you the desires of your heart. Psalm 37:4 (NKJV)” This verse specifies that the desires of our heart must be predicated upon the submission of our heart to the Lord. Whether it is fat, blood, pornography, adultery, drunkenness, or a move that is not the will of God, when God says “No,” we must respond with obedience and not disregard for His holy will!
