A New Cup

Matthew 26:42 (NIV)

 ⁴²He went away a second time and prayed, "My Father, if it is not possible for this cup to be taken away unless I drink it, may your will be done."
This cup is filled with the wrath of God in response to our sins.  We poured in the contents through our disobedience.  There was no one else who could drink this cup.  He Who was sinless took and became our sin.  He drank the bitter mix of ungodliness and emptied it.  
He then refills it with new wine.  "This is my blood, drink it in remembrance of me."  A new cup replaces the old.
