John 13:34-35; John 17:21-23

34 "I am giving you a new command: that you keep on loving each other. In the same way that I have loved you, you are also to keep on loving each other.

35 Everyone will know that you are my talmidim by the fact that you have love for each other."

21 that they may all be one. Just as you, Father, are united with me and I with you, I pray that they may be united with us, so that the world may believe that you sent me.

22 The glory which you have given to me, I have given to them; so that they may be one, just as we are one --

23 I united with them and you with me, so that they may be completely one, and the world thus realize that you sent me, and that you have loved them just as you have loved me.
