John 13:31-35

When therefore he was gone out, Jesus saith, Now is the Son of man glorified, and God is glorified in him; and God shall glorify him in himself, and straightway shall he glorify him. Little children, yet a little while I am with you. Ye shall seek me: and as I said unto the Jews, Whither I go, ye cannot come; so now I say unto you. A new commandment I give unto you, that ye love one another; even as I have loved you, that ye also love one another. By this shall all men know that ye are my disciples, if ye have love one to another.
