Are you enjoying the full benefits of that covenant? God is a covenant keeping God and He will not alter His words concerning the new covenant of the Blood of Jesus.
The importance of understanding the Blood Covenant is found in the fact that the basis of Christianity is rooted in a Blood Covenant. The Blood Covenant between God and Abraham, the foundation for the relationship of God to His chosen people, appears in the New Testament as a New Covenant, this time between God and those who choose to serve Him in Christ.
There's power in the blood of Jesus. The Holy Communion is a remembrance of the death and resurrection of Jesus, and His victory over the devil.
