Jesus’ death is:
•    Not accidental
•    Not tragic in ultimate meaning
•    Not failure
It is:
•    Divinely planned
•    Covenant-establishing
•    Substitutionary
•    Redemptive
•    Followed by resurrection and restoration

And Human failure does not prevent divine redemption.

Jesus’ death is the better Passover sacrifice that establishes the new covenant, occurs within divine sovereignty, exposes human inability, and leads to resurrection and restoration.

The Passover is a PATTERN of REDEMPTION both EXEMPLIFIED and REALIZED in Christ’s death: 
•    Deliverance through sacrifice – The demonstration of divine power that would overwhelm the powers that were in the world.
•    Liberation through blood – God’s people trusting in the blood as a sign of their faith.
•    Salvation through substitution – God placing judgment on the substitute for the salvation of people.

Communion is the ongoing sign that God has ASSUMED covenant RESPONSIBILITY. When believers take communion, they are not renewing their promise to God. They are remembering God’s fulfilled promise to them.

The PROMISE of RESURRECTION and RESTORATION REVERSES everything.
•    Death → Resurrection
•    Failure → Restoration
•    Scattering → Regathering

Jesus has just said the covenant will be secured by His blood.
Peter’s response effectively says: “The covenant will be secured by my loyalty.”

Peter is operating with an Old Covenant mindset: “If I remain faithful, I will stand.”
Jesus is establishing a New Covenant reality: “You will fail. I will remain faithful.”

Communion confronts this self-deception. 
•    We come saying: “I will never deny you.”
•    But communion says: “You will fail. That is why there is blood.”

Communion remembers: God has already fulfilled the covenant requirements. This is why the New Covenant cannot fail.  Even when we do.
