Leviticus 17:11

for the life of every living thing is in the blood. So I myself have assigned it to you on the altar to make atonement for your lives, for the blood makes atonement by means of the life.

The life of Christ's body is in His blood. This verse says that God Himself assigned the blood to Israel on the alter to make atonement for their lives. The picture of Christ as the sacrificial Lamb, His blood covering us and wiping away our sins, is the new version of this older covenant. Remember today that everything God designed for Israel, is a foreshadowing of His ultimate purpose to save us through Jesus Christ. Thank you Lord Jesus, for willingly laying down your life, so that we may be filled with your life.
