After saying this Jesus was troubled in spirit, and declared, "Very truly, I tell you, one of you will betray me." The disciples looked at one another, uncertain of whom he was speaking. One of his disciples - the one whom Jesus loved - was reclining next to him; Simon Peter therefore motioned to him to ask Jesus of whom he was speaking. So while reclining next to Jesus, he asked him, "Lord, who is it?"  

Jesus answered, "It is the one to whom I give this piece of bread when I have dipped it in the dish." So when he had dipped the piece of bread, he gave it to Judas, son of Simon Iscariot. After he received the piece of bread, Satan entered into him. Jesus said to him, "Do quickly what you are going to do."  

Now no one at the table knew why he said this to him. Some thought that, because Judas had the common purse, Jesus was telling him, "Buy what we need for the festival"; or, that he should give something to the poor. So, after receiving the piece of bread, he immediately went out. And it was night. When he had gone out, Jesus said, "Now the Son of Man has been glorified, and God has been glorified in him. If God has been glorified in him, God will also glorify him in himself and will glorify him at once.

Betrayal is one of the most painful of human experiences.  When I was young and more naive about life and people, I set out to seek only friends who would never betray me, the kind of friends who I believed would stand by me through all circumstances.  Likewise, I saw myself as the friend of my expectations.  Being full of my own sense of moral rectitude, I was blind to any betrayals I might have caused.  I rationalized away any hurt as a misperception of my motives for the greater good. 
 
We don't know what moved Judas.  Is it possible Judas felt he was acting on behalf of the greater good?  After all, he was trusted by the other disciples and he carried the common purse.  If money were his only motivation, he could have run off with the common purse, or hid it, and made up some story.  No, the evidence suggests Judas believed he was in the know of some greater good. 
 
Jesus was troubled in spirit.  He knew the time had come, and those who walked with him, who witnessed his miracles and heard his words of salvation, one by one would fall away in one form of betrayal after another.  As painful as the betrayal must have been for Jesus, what is more significant is how Jesus responds to being handed over.
 
Jesus' response to his betrayal was not to draw attention to the injustice of what was happening to him, but to proclaim the glorification of God through Jesus' life, surrender, and love.  Evil, even the evil of betrayal, is swallowed in the love of God.  God turns our brokenness into our wholeness. 
 
The readings show us, in Judas' betrayal, not only the human capacity for betrayal and brokenness, but, more profoundly, they also show us Jesus' love for us, a love which surpasses all our capacities for sin and alienation.  We have worth, we are loved, and we are forgiven.
