John 13:31-35
At the last supper, when Judas 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. Little children, I am with you only a little longer. You will look for me; and as I said to the Jews so now I say to you, 'Where I am going, you cannot come.' I give you a new commandment, that you love one another. Just as I have loved you, you also should love one another. By this everyone will know that you are my disciples, if you have love for one another."
