John 13:31-35

So, when he had gone out, Jesus said, “Now the Son of Man is glorified, and God is glorified in Him. If God is glorified in Him, God will also glorify Him in Himself, and glorify Him immediately. Little children, I shall be with you a little while longer. You will seek Me; and as I said to the Jews, ‘Where I am going, you cannot come,’ so now I say to you. A new commandment I give to you, that you love one another; as I have loved you, that you also love one another. By this all will know that you are My disciples, if you have love for one another.”
