John 13: 31 - 33, 34 - 35
31 When he had gone out, Jesus said, "Now is the Son of man glorified, and in him God is glorified;
32 if God is glorified in him, God will also glorify him in himself, and glorify him at once.
33 Little children, yet a little while I am with you. You will seek me; and as I said to the Jews so now I say to you, `Where I am going you cannot come.'
34 A new commandment I give to you, that you love one another; even as I have loved you, that you also love one another.
35 By this all men will know that you are my disciples, if you have love for one another."
