John 13

34 “I give you a new command: Love one another. Just as I have loved you, you are also to love one another. 35 By this everyone will know that you are my disciples, if you love one another.”

John 15

9 “As the Father has loved me, I have also loved you. Remain in my love. 10 If you keep my commands you will remain in my love, just as I have kept my Father’s commands and remain in his love.

11 “I have told you these things so that my joy may be in you and your joy may be complete.

12 “This is my command: Love one another as I have loved you. 13 No one has greater love than this: to lay down his life for his friends.

John 17

20 “I pray not only for these, but also for those who believe in me through their word. 21 May they all be one, as you, Father, are in me and I am in you. May they also be in us, so that the world may believe you sent me. 22 I have given them the glory you have given me, so that they may be one as we are one. 23 I am in them and you are in me, so that they may be made completely one, that the world may know you have sent me and have loved them as you have loved me.
