Mark 14:24
Jesus is referring to the New Covenant, which is explained in Jeremiah 31:30-34. The connection here is substantiated by Hebrews 8:6-13. It is by the blood of Christ that the Jews and the Gentiles may receive forgiveness.
Heavenly Father, you are worthy of the praise. How can we thank you sufficiently for your forgiveness? Without it we would have nothing, and we would be doomed. Thank you! In the name of the Lord Jesus Christ I pray and praise you, Amen.
