John 13:31-35

So when Judas had left, Jesus said, “Now is [the time for] the Son of Man [to be] glorified, and God is glorified in Him; [if God is glorified in Him,] God will also glorify Him (the Son) 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 told the Jews, so I tell you now, ‘Where I am going, you are not able to come.’ [John 8:21] I am giving you a new commandment, that you love one another. Just as I have loved you, so you too are to love one another. By this everyone will know that you are My disciples, if you have love and unselfish concern for one another.”
