John 13,31-33,34-35
When Judas had gone, Jesus said: Now has the Son of man been glorified, and in him God has been glorified. If God has been glorified in him, God will in turn glorify him in himself, and will glorify him very soon. Little children, I shall be with you only a little longer. You will look for me, and, as I told the Jews, where I am going, you cannot come. I give you a new commandment: love one another; you must love one another just as I have loved you. It is by your love for one another, that everyone will recognise you as my disciples.
