Judas, when he saw that Jesus was condemned – changed his mind – repented of betraying innocent blood, but was unable to undo the evil in which he had participated.
Was his sin that he had “betrayed innocent blood” or more like our sin: rejecting the way of the Messiah – thinking ourselves wiser than God and taking things into our hands?
Judas responds with despair.
God grant us hope, and true repentence.
Matthew 27:3-4 (ESV)
Then when Judas, his betrayer, saw that Jesus was condemned, he changed his mind and brought back the thirty pieces of silver to the chief priests and the elders, saying, “I have sinned by betraying innocent blood.” They said, “What is that to us? See to it yourself.”
